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?
 
Not if you keep the 19# injectors in there! I didn't see your other thread so I don't know what problems you may be having but... if you unplug the MAF while the car is running and there is no noticable (or very little) difference with it in you have just narrowed it down to a malfunctioning MAF. If it's just a little difference they may have sent you the wrong sampling tube. Otherwise your problems are most likely elsewhere.

As far as near stock idle and driving conditions, a 30# with your combo will just be a bit snortier on the high end, should drive just like you're always used to.
