Anything that writes to the ECM is trackable.

And don`t believe Hypertech for one minute on the claim that no EGT gauge is needed with the Hypertech programmer. Our tuner is safe,:eek: There was a thread sometime ago with several using the Hypertech with no gauges as suggested by Hypertech, towing and overheating on levels 2 & 3. Level 1 appeared to be ok. You really should have gauges especially when adding any power programmer. I installed my mech gauge 1 month after I bought the truck and was stock.

I sat in his office and we read the warranty over together. Now, I have the Extended Plan. He said that I had the best plan GM offers. I don't know what the regular plan says. Hope this helps ~Rookie Meeko 10-25-2009, 10:50 PM "The best GM offers" sounds like a salesmen to me Green Machine 10-26-2009, 02:53 AM Moved to Fourth Generation Duramax Electronics.

The extended plan is still covered by GM but covers everything from bumper to bumper (less Maintenance issues) for five years 100K. If they don't offer a better one, wouldn't that make this one the "Best"? Or do you have better information than I do? ~Rookie | ||
