I'm going to try to scan my dyno sheet tomorrow and put it up here. I made 283 rwhp and 323 rwtq. I have PS LT's and ORY and a Mufflex 4 inch. A K&N intake and a ported mass air feed the stock throttle body with an eBay special air foil. And I have an underdrive crank pulley. The car was pig rich at around 10:1 and then around 4500 rpm's it drops off the chart into the 9:1 range. The HP quit increasing at 4500 and flat lined and the torque lost its flat curve and nose dived and the same rpm. What do y'all think a good tune will do? They told me I was leaving 20-25 hp on the table. The uncorrected numbers were 289 and 329.

Those numbers sounds kind of low. I would guess about 310hp/330-340tq.

Did you have the car dyno'ed in stock trim?

No, but did you notice my insanely rich A/F ratio? They said I could make that power easily with a tune.

Looks like good numbers considering the tune problem. Can't wait to see what it puts down with a tune!

Uh this is an LT1 those numbers are right on as they should be. typical bolt on lt1s will not put down 310whp

If my scanner would work I'd show you my AF ratios and I think you'd agree theres more power to be had. I'll see if my g/f's scanner will work and hopefully we can get the graph on here.

Damn, that thing flattens out. I'm very curious to see how much is gained with a tune.
