Hooked up the Hypertech to the Tahoe and got a communication error with the throttle. I cleared DTC and tried again. it said return to stock and now won't go back. Programmer is now giving me a 7E code and shuts off. Anybody know what that means? On the bright side truck runs but it don't pick up or shift like before.
I'm thinking radio and amp come on when I turn the key could this voltage draw be affecting program?
