Yeah, it seems to be a complex system that varies upon application and truck setup. Idk, but I can say that if you are going to do mods you better be prepared to do them right. Thanks, I appreciate everyone's opinion. As far as the MAF and exhaust causing lean codes.
Probably both! I do believe my mechanic on the exhaust though. Not sure if I believe MAF being the reason. More like more air from the CAI. I am sure we will figure it out soon enough.
