Well I was on another sierra site till I realized the don't have that many members. I will continue to use both for resourses. Any ways I have a 2011 GMC Sierra and I bought a superchips programmer for it....and guess what there is not a tune available from superchips for 2011 GM gas trucks. But they have a tune for the Raptor, and the 2012 Camaro SS. Wha a crock.. Any ways if any of you guys have a suggestion let me know.
