A friend of mine was reinstalling his PPE tune and was unable to get his tune installed. The truck then threw 2 codes ;10c77f1a78000000,
10c73be5a27c6ef

If any of you know what these codes are or what could be his issue please help.

I forgot to mention that the truck won't start now and it just came back from the dealership.

i myself have never heard of codes that long...but im no expert..

if it came from the dealer and stopped running, probably a good idea to take it back to the dealer

yea either that or tell him to contact PPE, it may be a product error, most engine codes are something like p0403... hope he gets it figured out :thumbsup

This is why you should always reflash to the stock tune before you take the truck in to a dealer to be serviced....

Its why you should always see if there is an update available for your tuner.
