Shelby, MT
I put a superchip programer in my 01 and I went from 15 to 18 and a best of 22.....never really pull with it so I don't know. I have it on the lowest setting...the diesels have plenty already...My dad tryed one in an 03 7.3 and sent it back right away.....so all I can say is try it..if it works great...if it doesn't send it back and call it good.....
