hello all iam new to all of this i bought a 2001 dodge cummins about a year ago was thinking of putting a performance chip in it i sometimes pull a 45' gooseneck with farm tractor but mostly just around town empty thought it would maybe help on mpg it is a 6 spd 5.9 just don know what would be the best with out having to spend a arm and a leg thanks for the help

 

I would upgrade lift pump first and then put an Edge Juice w/Attitude. It has built in digital gauges on display. You can pick up one ebay fairly cheap.

 

x2 on edge juice, has everything you will ever need, and the ability to protect your engine

 

Food for thought: Once you add horsepower and torque to your engine, the weak links in the drivetrain will begin to show. #1: Torque Converter - you may develop chatter. #2: U jounts may go if they are worn. #3: Pinion Gear/bearing may begin to whine.

I have had a chip for 5 years and have found it to be the best addition to the truck. A new exhaust to enable it to breath a little better may be a good addtion as well.

Cheers..........
