Johnny and Supa, have you guys had any problems with boost drop/lag? I usually get about 7 PSI of boost but on soem really cold days the SC goe sinto safe mode and U get 3 PSI. I have had the knock sensor replaced already, that cured the problem for a while then it came back. I wnet bac to the dealer and I got the runaround from two different dealers. (the larger tires you installed are the problem and the aftermarket intake may be the problem)
