I have a 01 Cummins 4x4 auto that I have upgraded the trans, put a chip with gauges, 40hp injectors, lift pump, a cold air intake and put a engine brake on it. I am looking to put new intercooler boots, go to a FASS and upgrade the turbo. What components would you suggest? I pull an 11,000lbs horse trailer and a flat bed that I have had up to 18,500lbs.

 

Just look through my signature and pick n choose what you like. I've spent 10 years makin this truck into a daily driver that hauls heavy. Also spent a butt load a money on junk parts that have been deleted from my signature to.

 

a nice set of twins for towing and playing
