dyno'd gto today, swapped to 243 heads and add thunder racing comp cams 224/224 114. also swapped air filter box for generic cone air filter. I think the 06 exhaust setup added a little too.

Less than I have with stock heads and cam. Post your dyno sheet. Something is wrong.

Definately low, even for an a4. Those number are almost identical to my bolt on and stalled, high mile TA.

I guess independant axle doesnt help, but has to be the lowest h/c ls1 Ive seen.

Stock manifolds? Then they would seem about right

how much does the IRS eat up? My car is an M6 f-body... but that's less than what I dyno'd with just a tune and duals on stock manifolds stock lid, and even a paper air filter. Was there any knock retard or anything like that showing up?

exhaust is factory

SIC GTO

It's A baby cam with stock 243's thru a auto with factory exhaust. I wouldn't really consider it h/c or anything wrong with it...

It's not un common for a stock A4 04 GTO to make 270-280rwhp stock from what I've seen.
