ABOVE ALL THAT....

ASSUME THE DELETE PROGRAM IS COMPLETE GARBAGE!!!.. More than 90% of all delete programs out there are pure garbage and will severely shorten the engine life!.. Especially on a 600 HP engine!.

Bad programming (the biggest plague of the trucking industry) is as bad as having sand poured into your engine.. all while the truck owner usually swears that it seems to run good.

START BY copying the program from that ecm and e-mail it to me for a proper review of what someone did to it. Otherwise you are just trying to play the lotto of destroyed engines for no damn reason. Does not matter how it runs, etc. -= ASSUME THE WORST to start with and then go from there.
