The edge/attitude combo works really well. The other option is a "tuner" like a superchip, and some gauges. The ability to change power settings on the fly is nice, but sometimes allows one to get a little carried away. If you just install one tuner into the truck and leave it, I think its alot easier on it compared to changing power settings often. Either way, you will be happy with the added power. PM me if you want some more info, I can get you all that stuff.
