Maybe 4.10's will be in and out of boost so fast that you won't see full benefit from el turbo I suppose.

You can gear it as you see fit, but that steep of a gear and you will regret it.
3.73s are what I have and wish I went 3.54s. Transient response will be much better with the lower numerical gears.
If you want a tire fryer, and not see boost till third gear, 4.10s are for you!
okay i see what you are saying, definately dont want 4.10's, what about 3.42's? that is what is in the car now although in the stock 10 bolt which will definitely not be staying for much longer. honestly surprised i havent blown it yet knock on wood lol hoping to make it last until the winter which is when i plan on swapping in a s60. 4.10's seem to be a good gear for bolt on 6 speed cars, which is what i would like to have in the car now lol, but it doesnt seem worth it to swap gears in the 10 bolt now only to pull it this winter.
appretiate the suggestions snm!
so i seemed to have fixed the "miss" i was getting at part throttle when the car was warm. i ordered a delco MAF with the screen obviously and put it in the car and have been driving it for the past couple days without issues. as sslowboat had said it must have been because the MAF that came on the car was descreened by the PO and i never had it tuned for it. i also replaced the header gaskets that came with the pacesetters with a set of percy's multilayer gaskets as the pacesetters were cracked and leaking already after less than 700 miles. what a PITA that was, although i cant imagine replacing the headers with the motor in the car after doing this.
so the studdering/miss is back.....25%-50% throttle it stumbles, was noticing it most in 4th and 5th gear but it would happen in 3rd and 2nd. i took a crappy video that i am trying to upload. it has a screened MAF, new water pump, newer vented msd opti, i will check the plug wires tomorrow to make sure none of them are damaged. could my opti be bad already? i am at a loss and it is really annoying to drive when it is happening
also, i also need to hook my wideband gauge up so i can use it to datalog and send the files to solomon for some fine tuning on the tune. maybe i will try that tomorrow.
Well I always start with checking the same things.
First, lets make sure u have good fuel pressure... key on... idle... driving... wot... and when it is stumbling.
Once we have that we can move on with a bit of direction.
Also, does it have any SES?
FINALLY, I hate to say it, because I always want problems to be anything but the opti... but there have been lots of issues with MSD as well as other optis.
Ive had many lt1 cars... ive run many optis... accell (no issues, but did not have that car long). MSD biller, high rpm stumble. Dynaspark, many many many issues.
Currently both of my LTX cars are running AC DELCO Optis from American-powerhouse.
It is the ONLY choice for me, for optis. My camaro has never run better since she got the delco.
LTXtech.com IS my drug...
I bit the bullet and ordered a delco opti from AP, should be here soon. the stumbling started happening after I went through a car wash so I think that narrows it down pretty good....forgot to mention that part lol guess that should teach me to only hand wash it from now on. this will be the third time I've pulled the water pump and the second opti replacement since the spring...
also having trouble getting my wideband to show up consistently in the logs, I have been back and forth with Solomon troubleshooting the issue, but I am at a loss. I have a good ground (bolt on the firewall) and a good soldered connection to the AC wire to the PCM. going to check the AC wire from the soldered connection to the PCM connector to make sure it is okay.
so finally got the delco opti installed the other day and car is running better than it ever has. crisp throttle response, no more studdering and the chugging/vibration in 6th gear is gone. before 6th gear was useless until I was going at least 70mph because of the vibration and it would chug and bog down, but now I can cruise in 6th going 55 and without issue! hello better gas mileage! anyways I am a firm believer of the delco opti's now although still not taking it to car washes just to be safe. also think I fixed the WB issue, going to take some logs today to verify that I did. hoping it is smooth sailing until the car goes away for the winter and I can focus on getting the LQ4/4l80e swapped into my truck before the snow flies.
I noticed the same thing when my camaro got its delco.Quote:

ive had a love-hate relationship with this car and right now it is love lol hopefully it will stay that way from here on out. I got so excited for my new-found 6th gear awesomeness that I got a speeding ticket on my way home from work last night....didn't realize how fast I was going and next thing I know im doing almost 80 right by a cop using a laser, clocked me at 76 in a 55. ya live and ya learn I guess just gotta pay more attention
