For the past few weeks I have been looking into a custom tune for my
08 GMC Sierra 4.8L. I currently have 33's on the truck and plan on installing a 7" lift when I come home from AFG on leave. I also have a Edge Evolution programmer but it's not really what I am wanting therefore I have been toying with the idea of going with Black Bear. From what I have read everyone has been happy with the outcome once the tune is installed. Im looking for anyone that has got their 07-11 truck thats lifted tuned. Before and after thoughts. Also I'm looking at going with the AutoCal unit since I will want to change from off road to long distance driving. Thanks
