Is there a way to delete stored program information from the trucks computer? I had a PPE programmer on stage 3 six months ago and now I only use the programmer now to calibrate the tire size but no tune. I need to take the truck in for a glow plug code that keeps popping up and I'm nervous about them checking to see if there was a program... Thanks

No way…its a permeant record.

glow plugs are cheap at least if they say no way..

probably wont even check it..
