just wonderin, this guy had a blue one, so its obviously someone else, but obviously its a problem, i spoke w/ the powertrain engineer, he said its that damn heat exchangers in there doin it, they are too restrictive for the car, but gm wouldnt put something higher flowing in, they are losing 6 lbs of boost through them, on a car w/ a smaller pulley, it makes 20 lbs b4 the exchanger, but only 14 after, he also advised unplugging the wires to the bypass solenoid, or taking off the vacuum lines and plugging them, car supposedly runs alot better, gm is "supposedly" working on an m90 upgrade, and a traditional plate and fin exchanger upgrade, he said the m62 can make 300 at the tires on that car, but the exchagers wont allow it, also, a recommended upgrade would be a resevoir plummed into the stock exchanger that would allow for ice to be added, or alcohol and dry ice to be ran for those who want to cram more boost in reliably, o, btw the car w/ 14 lbs, picked up about 25 hp at the wheels for those interrested
