Does anyone know how I might put my 2003 Cummins computer back to stock settings without the programmer I used to set it to performace? The guy that tuned my truck moved away and I dont know how to get ahold of him to put my truck back to stock any help is GREAT!!!!

 

Dealer should be able to flash it back to stock. I'm sure it will cost you though.

 

Yea thats what I thought but I was really wanting another way because the dealer always rapes me!!! (not in a literal way )
