I used a Diablo Sport programmer to program my 2014 Truck several years ago. Last time I tried to reprogram the truck for a new tire size the programmer froze. After several back and forth calls with tech support i was able to finish programming tire size and exit. My question is, I no longer trust the Diablo Sport programmer. Can i have the dealer reflash the computer back to stock using their equipment? What i would like to do is flash it back to stock and buy a newer programmer to start over. I worried if i try to flash it back to stock with the diablo, it will freeze again leaving my truck inoperable. Any GM techs out there that know?
