The ADJUSTER by Attitude (pat pend) (formerly Attitude Adjuster) gives you full control of your 12-valve Cummins or any other engine equipped with a Bosch P7100 injection pump (4cyl, 6cyl, 8cyl) from inside the cab.  It’s a precise numeric-control-manufactured system with accurate command of range and fuel output.

Using the 3” in-cab controller, you have full precise adjustability to tune from optimum economy to maximum power.  It is adjustable for 8 dial settings and mid settings (16 total) through the fuel spectrum with only one rotation of the knob.  All of this is done while retaining the AFC housing (boost advance) which is crucial for drivability.

Because of its adjustability, The ADJUSTER by Attitude will work on every Bosch P7100 injection pump with no modification required; it has application for improving the performance of trucks from stock to highly modified.  The ADJUSTER is flow-bench and dyno proven.  The ADJUSTER housing also comes pre-machined for the shut-off solenoid bracket on ’94-’98 Dodge Rams.

The ADJUSTER is a drop-in part.  It’s a direct replacement of the cam plate and does not require removal of the injection pump. Installation is as simple as swapping a fuel plate.
