have you had any pcm tuning done after the cam install? if not that would be the main reason why your so lean. if you have had tuning done then yes a bad maf could also make you run lean.

The perfect afr ratio is 14.7 to 1 and you are running 14.8 to 1. I don't see what the problem is. Your afr is around where it is supposed to be, unless you want your engine to run rich!!

you are right during normal driving but i believe hes talking about WOT which should be around 12.5-12.8.
