my 6.0 wont run anymore it just wants to lope erratically then die. it was idling fine on friday fine finally. tried to drive it yesterday but wouldn't move just die. it is in a 91 fullsize. ive checked all my wiring twice over. just lost. im just not sure if its our end or the sd tune. it's not a final tune just a copy of the tuners tune with the same setup on his actual 02 6.0 p1sc charged motor. im just lost rite now.
