so change it all back to stock and put your stock tune in. My stock tune is exactly the same as it came. We checked it out last night with the screen shot and it does not I repeat does not differ in any way. If all of you are so worried about it then forget it don't do it and quit whining about it. Ask a lot of the G8 guys what is happening to them with warranty work and a tune. They still get it as long as the stock is back on the car with stock parts. They are not getting denied. One of the only vehicles I know of with gm that has the flash counter enabled is the duramax diesel equipped vehicles.
