I'm not a ford owner but I work on all vehicles I just had a 6.0 03 and a 6.0 04 f250 droped in my lap no one can figure out the 04 would fall flat on its face under heavy load replaced cam n crank seemed to take care of it. The 03 I done cleaned egr passages intake put egr valve waste gate actuator mps and new inner cooler cause it blew it out when backfired under load it still back fired reset kam n now nothing runs great so I need to know if anyone can tell me where the performance chip is installed r have anyone come across a feul comp going bad causing a similar problem ty
