Other tuned left me hanging- Diablo. Need some guidance with stock tune
Recently purchased a 2018 Yukon L83/6L80 and wanted to get rid of the dreaded AFM and get a little better drivability. Purchased a tuner from Diablo (Predator 2) Loaded the 87 tune and everything worked. I wanted to get a E-tune done so I reached out to a Diablo tuner. Said it was not a tuner he programs and to get the i3 tuner. Returned truck to stock with the Predator, returned it and purchased an i3. Went to upload the i3 tune and it says the ECU's currently have a Diablo tune on them and to flash to stock.
Dealer wants $300 and they "should" be able to do it. That is a lot of $ for a should.
Buddy has HPTuners. If I buy the credits, I know I should be able to upload the stock tunes into if I can locate the stock tunes. I see others have asked for these stock tunes, but I haven't been able to locate one for a 2018.
Can anyone point me in the right direction on getting a stock tune? I plan to have a tune done by someone at some point. I just would like to get back to stock for the near future. Returning this Diablo crap.
