I have a 99 2500 w/auto transmission. I tow a race car and haul all related equipment with this truck. Im looking for either a programmmer or some insight on some mild mods i could do for a lil more pulling power. Im just not up on which programmers work and which dont. I also want to try to keep from tearing stuff up also. What you guys recommend??
Thanks
Ray
p.s. truck has 297k miles if that matters.
