I've detuned the truck for towing, sold the SPS66 and installed a SPS62. I sold my Mach 8s and installed a set of EDM 200s. One is bad. I'm in the market for injectors, like right now. Which injectors for towing? Approx 6500lbs. Would still like to race the truck occassionally. Also in the truck are Drag Comp, FASS HPFP, Smarty, DTT trans.
