New HEX Code = New Custom Tunes?
So, I took my truck to the dealer's to get the airbag recall taken care of and, as I've known for a long time, my HEX code is a very old version. I reset my Gryphon to stock and unplugged it before taking the truck in, and I had the dealer update my PCM/TCM.
I haven't plugged my Gryphon back in, I do have lots of updates to my PCM according to the dealer.
Do I now need my custom tunes re-written?
