There is no "injection" pump on a 7.3 or any PSD up to the 6.4 CR.
You can do whats called the 10k mod, which adds a 10k resistor to the ICP sensor, making the computer think the ICP is low. This will give you about 10-30 more HP, but dont do anything without atleast a pyro.
HPOP= High Pressure Oil Pump, What pushes the fuel out of our injectors
ICP= Injector Control Pressure, the pressure of the oil in the HPO system
ICP Sensor= the sensor that reads the HPO rails...

The Injection Pressure Regulator controls injection oil pressure. An electrical signal to a solenoid creates a magnetic field which applies a variable force on a valve servo to control pressure. The quantity of fuel delivered to the combustion chamber is proportional to injection control pressure.
An open circuit will result in minimum oil pressure and a no-start situation. A short circuit results in maximum oil pressure, and is limited by a mechanical pop-off valve to 27,580 kPa (4000 psi) .

After Researching This I Found That It's All Electronically Controlled, Unless There Is A Program Given To Reteach The Regulator - There Is No Mechanical Way, Or A "Turn Of A Screwdriver" To Turn It Up.
The Pump Is Producing Enough PSI To Add Fuel To The Rail But The Regulator Bumps It Down Quite A Bit.
Hope That Helps

Not going to knock ya... but you could have built the same thing for about 2 bucks from some resistors at radio shack...
Very common mod on the 7.3, 10k mod, 18k mod...
Hell for about 8 bucks you can build the ajustable one like you bought! But make sure you have gauges, ICP mods will bump EGT's very quick!
