im gonna be getting my car dyno tuned probably in a week or 2. how much hp do you think i will gain with a good dyno tune. my mods are......

bbk longtube headers
o/r h-pipe
flows dumped
intake
vt stage 1 n/a cams
410 gears

my car maked 275whp untuned....what does everyone think i will gain from a dyno tune

2000GT4.6

what did the a/f ratio etc look like? If your making 275 on an accurate dynojet it doesn't sound like to me you need a tune at all.

The dynotune may not yield much hp increases at all. Driveability may get better, as well as gas mileage. Like 2000GT4.6 said, if your a/f is right on, then your tuner will do some timing adjustments and that may or may not make much difference in the numbers.I wouldn't expect much more than 10 rwhp.

a slight bump to the 280s. but hell, that could happen on a nice cold day without a tune. nothing you're going to notice.

It all depends on the car.I had stage 2heads/cams and all bolt ons andi went from 301rwhp to 310rwhp so i only got about 9 out of my dyno tune over the stock tune.

we will see.... i dont remember what my a/f ratio was. my dyno sheet is at home and im stationed in virginia so i cant go and look at the sheet. ever since i installed the headers and cams the car seems to be running real rich, you can smell the gas fumes pretty bad, and the car doesnt really like to idle that well. im hoping a dyno-tune will take care of it

it's the cams. when i got my new motor in with the new heads and cams, my car started smelling like raw fuel something fierce. the LTs that i just recently put on didn't affect the smell, just made it annoyingly loud.[:@]
