Ahhh, the monster 7.3L "Godzilla" great engine. Only issue thus far from what has been heard through the grapevine so to speak has been the spark plug/coil wires fail and give a CEL (Check Engine Light) for a misfire and trouble code P03xx which is generic for engine misfire. Other than that the new 7.3L gas engine is a torque monster and with a tune the beast will awaken. Add a turbo or blower and it is Mad Maxx proportions. Should be dubbed the HEMI Killer. In my opinion anyway.
