Presenting THE ADJUSTER by Attitude (pat pend) Part #1020 --- In-cab control of the P7100; from optimum economy to max power on the fly.
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.

- Increased Fuel Economy - 3rd party testing delivered 10-25% increases in mpg.
- Lower EGT's - A drop of 200-250 degrees in the mid ranges.
- More Boost - 3-10 lbs increase is typical
- Longer Pump Life - Great for highly modified or large pumps. Can defuel to under 150 cc's.
- Full rack travel
With one turn of the in cab control knob, you have full adjustability to tune from optimum economy to maximum power (to pick up and extra 2mm of rack travel, use APP's P7100 Rack Cap #1007). All this is done while retaining the AFC housing (boost advance) which is crucial for drivability. With the finite adjustment of THE ADJUSTER by Attitude, you will be able to tune your engine without leaving your seat!
Because of its adjustability, the 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 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.
Finally there’s a way to control your fueling from the cab. This product is 100% mechanical.
Attitude is proud to introduce the THE ADJUSTER by Attitude (pat pend) formerly Attitude Adjuster.

Suggested supporting mods:
APP #1007 Billet Rack Cap or bosch #2423462000. This will allow full 21mm rack travel; it is not required for lower operations, but is recommended to achieve greater performance and more horsepower from THE ADJUSTER.
APP #1006 Billet delivery .093valve holders. The #1006 flows more fuel andadvances timing. It’s also a great way to dress up your injection pump.
Optional Fueling Profiles: THE ADJUSTER is shipped with a #0 profile, but the following profiles are available and may be ordered from APP Distributors. (These profiles are dynamic for this part, not static; therefore we do not offer hp ratings, only recommendations for your application.):
APP #1205 (#5) Recommended for 13mm pumps and all heavily modified trucks
APP #1206 (#6) Recommended for most street trucks with modifications
APP #1208 (#8) Great for towing
