Hello went to a local guy using HPtuner that alot of local F-Body and vette guys use. Myself and two of my friends went today and all of us got dyno tuned. Just wanted to say thanks to clint from A.I.R here in colorado. I have paper graphs, ill try to take a photo and post them up. But the basics are. Stock 244.1 a common number. My max power on pull no 5 was 264, and the one on pull no.6 was 258. Not sure where my max tq lands. With the TQ lock vs unlocked. But on my 6th pull had a peak of 322.4 to match my 258.. But what was really awsome is that from about 3,000RPM's to 5,000RPM i gained on average 30hp

So know im addicted LOL, Cant wait to get a CAI, Throttle Body, and exhaust. I think with that might be close to 300. My budys Stock 2001 was put down 310 for a basline, and got it to put down 325hp and 350tq. IT WAS A GREAT DAY. Has anyone tested if just Mufflers/ or just a res delete has picked up power? I wanna wait to do a full exhaust aka larger Dia. pipe, rework the crossover tube, and down pipe, plus cutout.

Has anyone see such a big gain in the Midrange power like i did ....30HP

Can you post everything done in the tune

Panther427

a local GM guy did it, He had it tunned to this in three pulls. from watching him i know he smoothed the fuel curve and got my A/f ratio lookin almost flat at WOT. compared all over the place on the first pull. On my first run i was KR all over the top. Sorry guys i dont know much about how HPtuner works or any tuner.

anybody else notice how lean that was?
You have to remember too that if your stock tune is way off then you're going to gain more from a tune.

Yeah..thats crazy lean. Ideal a/f is 13.0, he is at 17.5

Nacho SS

iTrader: (4)

Woah 17.5?

I didnt even notice, both of you guys may want the !Tuner Mod and find a different one.

yeah to my knowledge 12.6-13.1 usually makes the most power. Not sure if a tailpipe Wideband causes that or what.

Nacho SS

iTrader: (4)

Mine reads from the 12.8-13.0 range.

If u look at the second posted dyno sheet. The line in the middle is the a/f ratio. I dont know why the number at top say 17.5Max.. Also according to the dyno operator/ which is different from the Actually tunner guy, his a/f ratio was almost a point lower than what it shows. so its showing 13.8 or so. take 1 to .8 of a point of A/F ration u would bein that good power range. Also if u look at the third grahp i posted. it shows the Stock A/f ration in red. and the corrected one in blue. The line that is fairly flat in the 13.0+A/F ratio area.

IF the car was at 17.5 i dont think it would even run.
