| Best thing i think would be a predator programer Ver. 2.02 on a low setting the predator is good because it adds boost also instead of just fuel and timing, and another great function is its ability to turn off the egr valve. The good reason for turning the egr valve off is to keep it from putting heat back into the cooling system and intake air which in the end will make the truck run cooler and longer!!!! THe added boost also helps keep egts down and make the truck a little quicker out of the hole! The predator makes good power and has really good features all for less the 400 bucks, but if you want to tow with more than the 60 hp tune i recomend gauges just for peice of mind!!!!
