I have been having a few problems after a cam and injector swap that some of you guy's have been helping me with. Well, yesterday, I swapped back in the 19#'ers and stock mass air just to see what would happen. After driving for a while, and bringing the idle speed up some, the problems seem to be gone. Now, I believe the C&L is to blame, seeming to not be able to compensate for the bigger injectors. (yes I did put the 30# calibration tube in) Would switching to a Pro M 80mm calibrated for the 30#'ers give me near stock idle and driving conditions?
