Can anyone at all point me in the right direction off "OFF ROAD USE ONLY" tunes for a farm truck with slightly less parts than stock. Every corner I turn is a dead end and I just want a few usable tunes. I know that EFI has stopped and so have multiple other tuners but I am really not trying to haul 10,000+ pounds on a +100hp tune without a lift pump and CP3 conversion. Even then I'd like just a mild 25-50hp tow tune as to not hurt the truck. PLEASE HELP!!!
