Stage 3 CP3... Who's got .. I got questions

I have installed a stage 3 cp3 today and have a few questions.....

For thise that have it ... are you seeing a SIGNIFICANT pressure drop off the line ... like down to 2000-3000psi off the line??? My truck feels like it has serious turbo lag... and its the lack of fuel to the rail. Once the RPM's are to 1500-2000 the rail pressure is up and the truck pulls like a raped ape. Even at 60mph on the hwy and mash it the rail pressure drops to like 4000-6000psi (from 18000-20,000)and then raises....? Feed pressure to the CP3 is a constant 24psi and only drops about 1psi at WOT.

MY STOCK CP3 HAD A BETTER PULL OFF THE LINE.

Is anyone else seeing this?

The vendor / builder has been contacted (after 1st test drive), and has suggested installing the stock FCA back in the stage 3 (dmax) pump. Please correct me but, is not the flow indicative of the inlet (FCA) flow and pressure? Or am I dreamin'? Is not a portion of the modifications to a CP3 flow the FCA modifications?

I tried pulling the EZ no change, tried all programs on the TST no change, ....\

Any suggestions?
