Has anyone had any issues with the standard 4" intake with 4" maf from pcmforless. We installed the base tune for it with hptuners and my idle was up and down with no throttle responses. Then reinstalled old intake and it ran fine. The file also had a tune for my new kooks header so just wondering if the intake tune might not have been in the file or it didnt take to the truck.

Im going to call them tomorrow anyway just wondering if anyone has had this problem.
