I got a question....

[popo8]

SINCE ive been looking for a replacement to my suv.... And ive always been close minded about diesels ..... Maybe i can have this question answered and help me change my mind.


At what years for fords chevys and dodges can u just buy those programmers to make the diesels FAST.

I dont want a race truck...but back in the mid 90s i drove a brand new cummins for work and it couldnt get out of its own way.....

THANKS IN ADVANCE.....

[Badbird_96]

My dad had a 2000 cummins 6spd dually extended cab 4x4 and he did some mod called low boost or maybe it was low fuel but anyways it tricked the pcm into thinking it needed more fuel so it dumped more fuel and he changed the boost to 28psi and took out the turbo silencer ring and it would spin the rear four tires in third gear. I think he said stock was 14psi or something like that. He said he couldn't do anymore on power as he was at the 6spds limit.

Don't hold me to those numbers as I'm pulling from memory about 4 years ago. But for sure it was a 2000 and it had power like crazy

[popo8]

Ok... I tried.... I went out I found a nice dually... they started it.....


I just cant do it... it just sounds like BROKEN to me...

[GreenZ96]

Try a duramax

[Badbird_96]

Oh now get a diesel and ltx swap :D

Unless you're completely stuck in gas engine mode, I still don't understand how a diesel sounds broken???

I'm not offended, I just don't understand lol. I understand that diesels aren't for some people.

It's just the fact that I don't understand how a diesel that's in tip top shape sounds broken lol

[popo8]

I'm not offended, I just don't understand lol.


You dont hear that diesel noise when yours is on? I posted a video...

[94Blackbird]

You dont hear that diesel noise when yours is on? I posted a video...

My truck sounds like a diesel, I guess it just sounds like a diesel to me. My truck sounds like it's purring like a big, sabretooth kitten to me lol. Maybe I'll see if I can't get a video of it idling tomorrow for comparison. Those 6.2s are going to sound a little rough though, they are really old diesels. The newer duramax's are super quiet, you almost can't hear the damned things.

To me that diesel snarl was always the sound of "do work son" lol


I'm not trying to be insulting or anything like that, there is just a serious lack of comprehension on my part of your point of view. I CAN see how it MIGHT sound broken if you were looking at, say, a buick, because buick's aren't supposed to sound like that, but in the context of a diesel truck, I just don't get it.

Again, not trying to be insulting or anything.

[popo8]

LOL... well it was the first video listed that made noise.....

You know what Im ref to right?

[GreenZ96]

Those Chevy 6.2 motors were dogs, lot of problems with them. I do however love the sound of a Cummins

[94Blackbird]

LOL... well it was the first video listed that made noise.....

You know what Im ref to right?

The only thing I can think of is maybe the sound of the compression ignition. Again, I'm used to how a diesel sounds, so it's hard for me to pick out a specific noise that might make it sound broken. I just know that if my wife's car ever sounded like my truck, I'd be pulling the engine apart to see what was wrong, because a gas powered hyundai shouldn't sound like a cummins.

[94Blackbird]

I love my cummins! lol

[Formula 350]

Any ford 7.3l Turbo would work for ya they don't sound all that loud and they can get out there own way. If you look into them there's alot that can be done to pep them up more. I drove a 03 f550 quad cab with dump box and it could move.

[shownomercy]

The new 6.4 ford stuff can be made very quick, but, they have iffy head gaskets and silly EGR/injector issues.

Dmax's just stay away from early motors with injectors in valve covers, I have an LLY which is amazing, 120hp tune and on 33s, pulls a solid 20mpg round town. Downside to GM trucks, weak trans and tie rods suX0rs.

Cummins, well, its a great motor, but surrounded by a POS truck.

But all in all, a diesel truck will be infinitely better than a gasser for towing and everything else. My truck has not a single care when pulling the car, and thats on a crappy uhaul trailer without brakes. Engine braking is great, and the allision trans does great for long hauls.

Very biased I am.

[sick70malibu]

Like blackbird said to me a diesel just sounds like its meant to work. I have a 7.3L Powerstroke in my Excursion and I wouldn't trade it for anything. If you were yo compare the early Cummins to a PSD or a Dmax the Cummins is easilythe loudest but it is also one of the best engines you can get in a truck. They are extremely reliable and pretty easy to repair. They can also make a ton of power. My friend has a 96 12 valve Cummins a bit of work to it and it makes 650rwhp and it is his daily driver.

My PSD is a bit quieter then a 12v Cummins which is nice and I love the sound of it. The 7.3 is the best engine that ever rolled out of the International factory. It makes good power and is extremely reliable. If I didn't have the 37" tires on it I couldeasily see 18 mpg in town and 23-25 on the freeway. If you can find a 7.3 for a decent price I'd consider it. The auto trans behind the 7.3 is ok but could be a weak link if you start stacking chips etc. The 6spd is awesome behind it a couple of my friends have 6spds in their trucks and its great.

The thing about the diesels is the compression ignition is what gives it that knocking sound but once you get over that you will never go back to a gas truck.

I'll make a vid of my truck for you tomorrow so you can hear it run etc. Hope this helps a bit.

any thing with duramax name you can tune . While the early duramax has the injectors buried a lot of people think they are the better ones because of the lack of emissions on them. The 6.0/6.4 and up powerstrokes are also all tunable. I believe you can tune the 7.3 but again a lot of people like them for there lack of emissions equipment.

I agree I have driven the more modern diesels and while not as bad as the predecessors they are still loud to me. To me it isn't the sound of work its the sound of using compression to ignite the fuel which is exactly what it is. I think hearing the turbo consistently is the biggest turn off for me. The clunking does quite down after the truck does warm up.

I know that someone will say that I am wrong but I feel they are way over rated. There are a lot of drawbacks to them and they are very costly to buy, own, and operate. Unless you have an express need for one I would say skip it and the reality is most people don't actually NEED one.

[sick70malibu]

Almost forgot to add that just about any of the diesels with an OBD2 port arr tuneable. My PSD is currently on a mileage tune and I can still smoke out an intersection at will. When I put it in extreme mode that when things get really fun really quick ;) 37x12.50 tires smoking down the street anyone?

AFAIK, there is NO tuning support for the newest LML stuff, so, it would be wise to stick with pre DPF trucks.

If you are buying a 2500 truck, you should be prepared for the heavy maintenance costs attached to it, diesel or gasser.

Can you store 5 tunes on a gasser pcm and switch on the fly? nope.

Why in the world would a turbo whistle turn you off....?

[popo8]

ophhh, I didnt mean to start a battle about if diesel is good or not....

[shownomercy]

There is no battle, diesel >>> gassers. End of story.

Only battle is whether you really need/want one.

[popo8]

Lol... Ok diesel is better than gas.....

when I drive 10 hours 600 miles in one direction like I do on a regular basis for my one job I don't want to hear a loud clunky engine nor the spooling of turbos climbing hills and stuff. I had a 6.4 PSD last week. honestly It didnt impress me power wise nor on fuel consumption plain and simple this was towing approximately 10k pound load. My v10 is dead and I mean dead quite inside.

Yes actually you can get power programers for gas engines form bullydog. The reason they dont offer 5 tunes is because well you dont need them with a NA engine.

My personal opinion is don't mess with it if you get one. I think I have the willpower that I could get a couple of things for one to increase fuel economy and keep my foot out of it and use it for what it was intended for. None of my friends have managed to do this however. Burning up clutches, etc. It seems silly to put unnecessary wear and tear trying to go fast in something big like that (although it absolutely possible) when you have a car designed for it.

Ignorant statment

Its all opinion, with a little bias thrown in. What kind of mileage do you pull in with the V10? I don't own a ford PSD so can't really comment, but they are loud engines. My dmax is damn near quiet at idle and other than the turbo whiste its pretty tame. Cruising highway you wouldn't know its a diesel. Only really hear the turbo cause of the mods etc anyways.

[AdamG]

towing the loading 10k I averaged about 10 mpg and about 13 average my speedo is a little off so Im not sure if that favors me or hurts me. I don't hand calculate it either so again not sure of the accuracy. It is time for a tune up when I bought it i was doing about 2mpg better average and about 1 mpg towing. With the powerstroke I had this last week I averaged 14-15mpg. I accidentally reset the average and it never went back to 15. Obviously that is a 5mpg difference between the trucks. But I put 87 in my v10 and i notice any where from a 35 cent to almost 50 cents difference in fuel prices depending on the area. I really couldn't gauge the difference between the tanks because I have 31 gallon tank and the PSD had the big camper tank. so its not like I can say that that i noticed a X amount of difference on fill up.

The V10 has 362hp and 457trq and psd is 325hp and 570 tq. Honestly I didn't really notice a difference going up the hills. I notice my truck would down shift going up the really steep long grades where as the diesel would tend to hold the gears. But my truck is able to run the gears out a lot longer and take more advantage of those lower gears because of its higher rpm capabilities. my truck redlines at just under 6000 where as the psd is tapped out at around 4200. but I dont feel that either truck struggled going up the steep grades and neither slowed down at all. most of the time my truck doesn't down shift. The big thing I did notice was the lack of an engine brake on the PSD. When I go down a steep hill and the load starts pushing me the v10 will kick on an engine brake and hold back the load.

A guy at work had his tuned and claims more power and mpg out of his v10 Mine is stock except for the lift kit, plow, remote car starter and honestly I don't want to mess with it. It runs good and does everything I have asked of it and never seems to notice it. Prior to this I had a 92 gmc that had a 230hp v8 and it towed a lot of stuff but struggled. when I sold it my v10 towed it to its new home and didn't even notice it behind it about 7k pounds between the truck and trailer.

the turbo on the psd is right just about right under the dashboard. when i buy a new truck I may just get a dmax just because while i like my ford drive train, interior and all around styling. the ride and the quality of the rest of the truck leaves something to be desired. I would have to see what engines chevy offers at the time and try them out before I make a decision. Plus it depends on what I need my truck for when I buy a new one. I dont drive my truck except when I am towing, hauling stuff in the bed,plowing, or bad snow storms.

Again I dont hate diesels I actually do like them for the right place and the right job. I just feel most people don't actually need them. Kinda like most people don't need a dually but insist on having one.

[shownomercy]

Yea, the dmax has the turbo right by the firewall as well, only one that doesn't is the cummins, think its down on the passenger side, straight six silliness.

Ricer math wise, my truck should be 425hp/805ft-lb, which certainly makes the truck get out its on way, downside, can't tow on that level, but even the tow level is great. Engine braking is great, if you drive it cautiously you really never need to use the brakes a lot. When I tow my camaro, the truck gets a consistent 15mpg, and thats usually booking it ~70mph lol

I do about 70-75 depending on the state I am in. I dont need and engine brake its just nice and takes a lot of wear out of the brakes. it uses the engine to keep a consistent speed which is really nice when the cruise control is on because the computer does everything.

there is a guy on the ford forum that turboed his v10 with about 5-6 psi of boost on a rear mount turbo no inter cooler. He saw a 100hp and 130tq increase and claimed a slight increase in gas mileage when towing and around town. I am highly skeptical on the fuel mileage claims though. Oh and the turbo was barrowed from a cummins diesel lol.


My father wanted to drive my truck a few months ago. we are siting a stop light and he looks over at me and tells me my truck stalled and grabed the key and tried to restart it before I could say anything. Good thing it had an ignition safty LOL.

[1QUICKZ28]

I have 2005 Chevy Silverado 3500 crew cab dually with the D-Max LLY and Allison tranny. I can tell you from experience that all three of the big names can only handle so much before things break. The Allison tranny is good for 80-120hp over stock. The 120hp tune is pushing the limits. The weak point is the converter. Ford has same issues and well Dodge is finnally getting close to a decent tranny. Leave them stock they run forever. Average maintenance is $2000 a year depending on mileage driven. Which ever brand you pick, before you program do lots of research on how much the stock stuff can handle. I have taken out my head gaskets, heads and tranny. It's a VERY EXPENSIVE hobby when you start playing with a diesel. I have about $15,000 in my engine and drivetrain now. I built the tranny to handle whatever I throw at it and a defective clutch disc in the billet triple disc converter let me down. Out came the tranny for a second teardown. The converter company took care of parts only and no labor. OUCH!!! So the programmer is off now and thats how I'm leaving it. Can't afford to keep breaking it. BTW- ran like a raped ape when all was working with over 1000 foot pounds of torque. It's a whole different feeling from a well built car. It's fun to go out and run side by side with some decent built cars or even beat them and piss them off. I've always pulled a 10,000 pound camper on stock tune and I can drag it all day long 75-80mph up hill without breaking a sweat. Towing a car is like there's nothing there. Mine isn't that loud and really couldn't hear turbo much until I put a turbo down pipe on it and deleted the cat. I personnally like the turbo whistle. It all boils down to what you want to do with the truck and what your funds are. Be smart and all will be good.

k... so from what Im seeing, DIESELS have the majority of the positives IF.... money was no object.

Im not looking for a race car, just a DD, and I figured if Id buy a diesel, Id turn up the wick (ALL THE WAY) with a tuner... I did not realize the limits of the tranny etc, were already sooo close to the limit.

I think Im gonna stick with a nice SUV.... still really thinking about that 6.0 liter escalade...

[Badbird_96]

As far as gas mileage increases my understanding is because it doesn't have to run as hard to be at the same level of performance as it did n/a.

As far as trannies yeah especially the 6spd Cummings. You can add about 100 HP and its on the ragged edge. Surprised my dad didn't break his before he sold it. Its the torque that kills them. Put 600 ft lbs on a stock 4l60e and see what happens lol

You have to remember that 100hp tune in a diesel gives you anywhere from 150-225 additional foot pounds of torque. My D-Max is rated at 605ftlbs factory. Add another 150-200 and you got a torque monster. Hell the new models are pushing 750-800 ftlbs now. I had an 2002 2500hd with the 6.0, 4l80E tranny and 4:10 gears with 35's. Towed good but felt like I was beating the guts out of towing my camper thru the mountains. Turning 4600-5000 rpms constantly while pulling hills but that seems to be where they make power. That's why I went to a diesel. My wife has an 05 Yukon Denali that we love but I never towed with it. Doesn't have the gears my truck had. I wouldn't be afraid to thou. 6.0 is a good engine and you can't go wrong with. I had a tune, CIA and shorty headers on my old truck that really woke it up. Either way you go I think you'll be happy.
