The Computer will change after 500 miles, allowing more "boost" and HP to the wheels.

Hmm...I guess that means I have about 60 more miles to go (I have put 440 miles on it since picking it up from the dealer last Friday night)

Took it to the dealer and tech said he didn't know wat it could be. Also when you get on it in 5th gear the turbo builds up to 10psi and my foot is mashed down the whole time it with go to ten real quick then go to 5 then ten again when it should maintain a constint boost anyone having this problem to? Its a 08 SS/TC anyone having the same prob or suggestions? i need to know so i can get this fixed.

For the first few thousand miles that I put on my 09 SS/tc I was having some type of boost problem. in any gear under WOT the car felt like it was giving me whiplash, and my RPD showed boost going up and down, and then back up and back down, and same with my HP guage. I took my car in to the dealership multiple times and was even pursuing lemon law because noone could fix the problem. The car actually fixed itself at around 6k miles. It ran fine for about 6 months and then for 1 day I had the problem. Since then I've been driving for about another 6 months with no problems at all. I know this doesnt fix your problem, but at least your not the only on that had problems. If you ever find a fix for it, I would be interested in hearing what the problem was.
