Ok..I no longer own my truck in my signature. I sold it to a good friend. So far he has put a bts tranny and one of their 6 position chips along with 5inch straight pipe. He called me today and wants to go sled pulling in a month. What other mods should we do to gain more h.p. They only thing is we use this truck to pull our backhoe around sometimes at work so we don't want to make it to wild. I was thinking aftermarket hpop, ats housing, lift pump and shim the regualtor. What do you guys think would work best for both uses. Thanks!
