Quick question: deprogram Hypertech ECM code for ext. warranty service?
All I use the Hypertech for is to kick the fans on earlier. Car goes under the knife in the a.m. for auto trans diagnosis, have GM Major Guard ext warranty... Hypertech claims their programming does not void warranties, but should I take the chance?

I would change it back, just to make sure they dont say anything.
