I bought a Sct tuner from stage 3 with custom tunes from 5star. Just have a question, when the truck programs the canned tune the radio speaker makes a loud pop and all the power to the truck is cut off. After it finishes programming everything comes back on and it says service advance trac, then that goes away and I had to reset my clock and my auto unlock door feature, Is this normal? The truck runs great with the canned Sct tune, can only imagine how its gonna be with the custom tunes. Just seems weird how it cuts power and resets everything. Only other tuner I have had is a edge evo and it didn't do that but that was on a older truck.
