Turns out it fits GM D-Max's, Electronic P-Strokes, and 03+ Cummins, not a 99 VP44 truck, or any VP truck for that matter. Reads Fuel pressure, RPM, Boost, and EGT's. Has a heads up display that is changeable on the fly. Looks like a really nice unit, but its of no use to me. Retails for $450 new.

 

still have this?

 

Yeah, shoot me an offer, I'm flexible, just gotta get rid of it.
