from my Hypertech level III tuning! I detuned the truck back to stock as I'm going into the dealer next week for my last warranty visit as my B2B is going to run out in about 600 miles. The dreaded intermediate shaft rattle is starting to come back after being "fixed" 15k miles ago. The truck has never been updated so I don't have the fuel filter change msg, etc. I figured I'll put the factory tune in & drive it for 4-5 days. I'm going to also try to get them to do the #2 & #7 harness fix. I've had good luck with them over the years so hopefully they'll be able to accomodate my request..:D
