Dealership flashed my truck took tune off

[Alexpaul09]

I have a 2014 with the 6.4 and a diablo tune so it shuts mds off. I took it in for some recalls and I never told them it has a tuner on it. Well they re flashed everything and now my tuner says not compatable with this truck. I've updated it and everything and it still won't work. Any suggestions?

Most likely going to have to call whomever you got the Diablo tuner from and send it back to them to have it unmarried and the tune put back on it that you had.

^^ and that’s why you detune before going to the dealer.

I might consider buying a spare PCM to help avoid having that issue again. Takes all of about 10 minutes to swap one in these trucks.

FWIW. since I am coming from an ED with a lot getting GDE tunes, a lot of them were actually keeping their stock ECM and putting it back in when they went to dealer. I have no experience ref tuning a gas vehicle, so no help there. Just putting this info out for folks...
