If it is an LS2 I would think the numbers should have been closer to 375 hp. That is figuring with the mods it most likely is around 440 at the flywheel and then figure a 15% lose puts it around 375 number. Now we all know that different dyno's give different numbers, but I still think this one is off. Did you do a pull before the mode?

Year of Vette?
Auto A6 or A4 (if 2005)? Stall in Auto - locked or Unlocked on Dyno run?
Rear gears on Auto?
MN6?
Do you know the type of Dyno? Mustang/Dynojet?
Do you have the Dyno chart? does it have the AFR on it too?
Thanks,Matt

Those look like LS1 numbers.....Or bone stock LS2 #'s. I would be pissed if my LS2 was throwing those #'s down after those mods. I'd throw in the towel and get an LS3 vette.

no offense but those canned tune are junk,,,i never had any luck with them...think about it..it was a tune developed from some data that the mfr'r has or has developed and it is hoping that regardless where you live (geographically speaking) it will adjust your ecm to work better...makes zero sense to me.i went back and forward with the customer rep three times,,i sent him my datalog, he would change it a lil bit, i would re install it ...did this about three times and got tired of it...thing is it could damage your engine because of not knowing how the engine would react........i took mine off sent it back got my money back and went to a dyno shop and got the perfect tune..something to think about..

Yes, I don't blame you for being upset with those numbers. I have ARH long tubes, X-pipe with hiflow cats, and a tune. These were on the car when I bought it, but talked with a local tuner that had a great reputation and he feels the it is most likely 440-450 at the crank and around 375-385 at the wheels. A6 and it is sideways at the first to second shift and chirps the tires when it hits third.
