What you are buying is an adjustable fuel pressure harness for a late 2003 to 2010 Cummins ISX engine that has/had the EGR or DPF. If your engine has the DEF system this WILL NOT work.
It comes with a 10 position control knob that mounts in your cab and connects to a harness that is connected to your fuel pressure sensor.
It is 100% water proof and designed to handle the underhood tempratures produced by your engine. Increases in power are adjustable from stock hp to 100 plus gain, Torque gains have been as high as 250 ft lbs.
This set up will increase your fuel mileage anywhere from .5 mpg to 1.75mpg. This harness will wake up your ISX and give that extra fuel mileage that is needed.
Harnesses are professionally built and tested before shipping. This product is made in the USA and carry a limited warranty. If for any reason you do not like the results, I offer a 100% money back guarantee. Simply return the product within 60 days for a full refund.
