07Bluecobra Posted June 24, 2011 Report Share Posted June 24, 2011 Hey guys, I have an 07 GT500 with an FRPP CAI/tune package, and stock pulley. Do I need to re-tune to install a smaller blower pulley? If so, can ford do this for me on my procal? Thanks Link to comment Share on other sites More sharing options...
08 Mustang Posted June 24, 2011 Report Share Posted June 24, 2011 Yes, you'll need to retune the car. I'd recommend finding a local, reputable, shop in your area to talk with about reprogramming the car for the smaller pulley. Link to comment Share on other sites More sharing options...

cluscher Posted June 24, 2011 Report Share Posted June 24, 2011 I have a Lund tune and didn't need a new tune with the pulley. Your CAI tune should be good to about 13 psi. Link to comment Share on other sites More sharing options...
