  1. I guess the problem I'm having is the truck has amp powered running boards that plug into my obd port. I bought a splitter from amp and plugged the running boards and the range in that I have but then the radio went haywire. That's the only reason I was thinking of a tune.
  2. Good evening, I have just purchased my first GMC truck its a 2018 sierra Rocky Ridge K2 with the 6.2 with 65000 miles. Two questions I can have a local shop put a program to turn off the AFM or should I use the range chip?? Next is I got in my truck today and the Radio was going haywire luckily I bought an extended warranty through my credit union but is this a common thing??
