I am extremely pleased with Torrie's tune. I am using the Ford Racing pulley because I like the OEM look of it. This may or may not be important to you. I believe Heffner's pulley is also anodized black. Torrie can provide a tune for whatever pulley you get. If you don't mind spending additional money, I suggest getting the complete FRPP tune/pulley kit, use the pulley and spacers from the kit, and install a tune from Torrie. It think it is worth the extra money to have the FRPP tuner and tune, which is 50 state compliant, should you need it later. Also, who knows how long Ford will offer it.
