Thank you all for your input. The car is going in the morning to the saturn place, but I had my friend at the GMC/Buick place read the code and it ends up it is saying the solenoid that operates the wastegate on the turbo may be cracked. Apparently this must be a problem, since in November Gm created a bulletin about it. The cold air intake that I ordered was specifically for the Red Line model, so it shouldnt (operative word being shouldnt) have caused the problem. What I think has happened now is where the removed the old intake and the connecting piping, they may have damaged the solenoid doing so, causing the failure of the wastegate, preventing boost... hopefully that is all. I guess we will find out tomorrow.
