Has anyone got this going back to stock from a tune?

[SCAR911]

Long story...but I had to go back to my stock tune again. Other was not working. Got the truck back with the. Normal method with the Cobb and all was fine. After a few hours of driving the truck started to shudder horrible. Shifting was all screwed up and the speedometer was off. I got this cel. Is there a way to fix this myself?

I had that once, had to to update the tuner software. I’m not very techy and figured it out. Plug into computer via cable and go to Cobb website. Was pretty easy. Then that cel will clear and accept tunes
