customer came in with a procharged gto. 2004 model with the d1sc tuner kit. has the 3.7 pulley with headers, exhaust, decatted, mild cam, bbk intake mani. and 80mm throttle body. all piping and bypass valve checks out. only problem its having is that its only boosting 1.5 to 2 pounds of boost. any ideas? belt tension is good, belts are good, bypass valve is good, about 1mm of shaft play on the actual charger itself. procharger told me its about right to only boost 1.5 to 2 pounds of boost with the current mods but for some odd reason, i dont buy it. i think the charger is dead, any comments or opinions?
