Just got my custom tunes today from the shop. Bill, you're dang good at what you do. Many people get frustrated because it takes longer than excpeted to get there orders filled. All i can say is patience patience. If you cant reach Bill by phone or email, just try the forum at 2:30 in the morning. Lol. The truck drives great now. No skipping, nice performance for a 4×4. I couldn't help but take on a new GMC Sierra two wheel drive coming home to test the custom tune out. Lets just say i let him catch up at 70 mph just to see the look on his face when i blew his doors off.....again.
I began questioning the avg mileage reading on the programmer when i noticed i was getting 19.5 mpg at 75 mph! Awesome!
