DPS MAP Sensor Regulator Kit

7.3L Powerstroke

The computer/programming on a Powerstroke engine senses the boost that the turbo is producing with a MAP (Mass Air Pressure) sensor.  It is set up so when the turbocharger produces over 25psi of boost, the computer will set a code, turn on the Service Engine Soon (SES) light, and try to cut fueling to the engine to keep the boost at the factory level (25psi or lower). 

This is not a problem with a stock engine, but becomes evident when you add a chip since most chips increase the fuel delivery to levels that can produce well over 25psi of boost.  The computer setting the SES light and de-fueling is annoying and hurts engine performance.

The MAP Sensor Regulator kit installs between the intake manifold and the MAP sensor.  The regulator comes preset to only let the MAP sensor "see" 23psi of boost and thereby prevents the computer from de-fueling or setting any codes/lights.

Our kit installs with basic hand tools in only minutes.  It is also fully adjustable should your truck's setup require it.

The kit includes -

• Professional grade pressure regulator with gauge for easy re-adjustment. (pre-set at 23psi)
• High quality high-temp braided hose
• Complete installation instructions
• Mounting bracket for regulator
