Flashing a tune accessory or service mode?
Getting ready to tune my 17 Yukon. This is the first vehicle I’ve put a tune in with a push button start. Should I put the truck in accessory mode or service mode for the flash? Just don’t want the power to cut off in the middle of a flash. What has everyone else done? Thx.- Tyebo185

You got your answers, but with my experience 2017 Yukon with the 5.3. I purchased a range device to plug into my obd port. Mainly bc I threw an exhaust on and couldn’t stand the sound when dropping to 4 cylinders. I probably did that around 80k miles. Well here we are at 94k miles and guess what...- Tyebo185
