Been thinking lately of getting my 5.3 Silverado tuned since I have lost gas mileage with the new tires and it could be a little more responsive power wise.
I'm worried about voiding the warranty with the tune. Anyone work for GM or have dealt with this situation before that can give me a little guidance?
Thanks
