2012 Silverado 5.3

Post by Bowhunter46975 »

I have a 2012 Silverado 5.3 and I bought a predator 2 tuner. When I received it I updated on my laptop and when I plugged it in it says calibration files not stock. So I sent my truck into the dealership and had it reprogrammed and it can back and still says calibration files not stock. Is there anything I can do about this or am I not going to be able to use the tuner? I'd really hate to have to send it back.

it should ask you to contact us?
We can fix it, just give our team a call, 561-908-0040
Sounds like the dealer either didnt actually flash anything, or its the TCM and they just flashed the PCM, etc.

the dealer didn't flash both the ECM/engine and TCM/transmission modules back to factory stock programming...
