My 99 coupe made 327/333 with those mods on what they claimed to be a "conservative" tune. That was from a shop down south were I bought the car. I think you can see upwards of 335 or so.

I made 336/336 corrected with LS6 intake, ported stock throttle body, vararam, GHL bullet cat-back, and TTP tune, on stock exhaust manifolds and stock cats.

Depending on the type of dyno and transmission 325-350 whp is a good estimate.

i only disagree with one statement. that the postee had made. a GOOD tune usually involves a dyno which you would have your hp numbers...
