New to this forum and new Duramax owner. Trying to get info on tuner, traded for 2011 GMC supposedly has tuner, but all i see is 5 position switch on dash. Could someone help or should i post in different area.

Post up a thread in Tuning/Logging/Gauges. Doubtful anyone will know whose tunes are in your truck, but you never know.....
