07 f150 5.4 3valve with new 08 engine 5.4 3valve out of 07 expedition, with 04 f150 4wd transmission, and original transfer case awd/4wd for Harley truck. Using pcm from Harley f150. Starts but in limp mode, cannot hook up d8 xtool scanner it wont read anything- no comm issue. Do I need to reprogram eeprom or should just see if dealer can reprogram to a 4x4 selectable instead of awd/4wd? Possible? Or am I sol?
