I'm pretty sure it reflashes the programming in your ECU. The software would then command more fuel.

The Computer can only demand so much fuel from the VP44. Thats why the Smarty only adds around 65hp to a VP44 truck. In order to make more power you have to use a box that taps the pump.

If i were you id tap the pump for the ADR and run smarty with no timing. With the money you got in your truck... whats another 1500$ for a bad *** Injection Pump?
trust me i need a new injection pump. i just cant choose witch one i want! im prob gonna try the S/O
