I just bought a fellow member on heres GTO via a local dealer. He had the following done to it; K&N intake, Kook's 1 3/4 headers with high flow cats, Flowtech custom camshaft 330/228 * 113 (including springs, pushrods, timing chain, crank bolt) Complete SAP package including rear spoiler (minus 18" wheels). I test drove it today with 3 ppl in the car and a 1/4 tank of gas (could have been regular knowing the dealer). The car was partially de-modded, it has the cam, an x pipe on it, the sports apperance mufflers but headers are gone, high flow cats I believe and headers are gone and the intake gone. I used to own a C5 auto and my friend has a 2001 z06 with intake so I am pretty familiar with how fast the car should be. The car has nitto 555's also. Well on full throttle it just did not seem anywhere near as fast as I expected. It didnt even come close to going sideways when I shifted, didnt chirp the tires from a 30mph roll, and just didnt seem as fast as I would expect a stock one to be. Do you guys think the car is knocking like crazy and starving for air with the cam and no headers and intake? Im pretty concernded and thinking of backing out as I have till tommrow for delivery of it. Anyone help would be greatly appreciated.

PS it was also dyno tuned and was running 415whp before the mods came off, I was told it was re tuned after the de mod but Im not sure if I believe it.
