My boss has...I believe, a 2005 GTO...and it sounded alright, put down the power, and is now close to getting supercharged (for some reason). but I wouldn't have one, it's too cookie cutter for ME. We raced down our parking lot one night after work, and my car kept up pretty darn nicely with his 90mm throttle body... he just couldn't beat me on the start! He did start closeing in slightly towards the end, but we had to slow way the heck down since a sharp 90* turn was coming up! that's when my car ran awesome, and I was past the 5,000 mile babying stage... Coincidentally, he hasn't talked one bit of crap about my car since.
