All cars and tunes are different...you might gain 2rwhp or you might gain 20...

There is always no 'Guarantee" on how much horsepower a tune will give you but usually it will be more than 2. the lease I have seen on a basically stock set up is 8 and the most I got out of a car was a Bone Stock C5 and he gained 36 RWHP..

I watched almost the same thing happen on a basically stock 98 vette - WOT fueling was so rich that it looked like a diesel. Tweaked in the PE and then adjusted the VE table - that thing came alive !!!!

Well I have a 3800 stall also if that matters. I will get it dyno tuned in a few week's and I will be taking it drag racing for the first time before and again after I have it tuned. I will post Dyno result's and race time's on this thread for you's.

when u do ur power pulls make sure the converter is locked up in third. u should make close to 350 rwhp with that set up if the tune is right. and also u will be at the end of the stock injectors. u should be 29 +/- 1 degree timing and 12.9ish a/f with a good tune up on a power pull good luck

like when your tuning for wide open throttle if ur lookin for the biggest number make sure the converter is locked up. while the car is running using the hptuners scanner u can manually put the transmission in third and lock the converter then u can hit the gas and record data. when the converter is not locked up it is slipping loosin power to the wheels just gettin used up creating heat. so lock it up.
