7.3 Ford Powerstroke Diesel boost fooler kit prevents over boost defueling with this easy to install big boost modification. Over boost codes at between 23-24 psi set by truck with performance modifications like a performance chip or performance injectors results in computer defueling and trouble codes at those higher boost levels.  When the computer defuels, the injector performance is reduced while the computer is in defuel mode.  

The boost fooler allows the truck to function normally but tricks the computer by only allowing it to see lower normal boost levels.  This is a inexpensive and simple product that is a must have for any modified truck.  It is installed inline with the truck's map sensor and it's preset to 22 psi.  When the boost levels reach this pressure the valve releases and the map sensor only sees the 22 psi of boost although the truck is producing more boost and power.  No more trouble codes in the pcm and no more defueling.  

***This product will only work on modified trucks that produce more than 22lbs of boost pressure. You will not see any benefit from an unmodified truck!
