Rising Rate vs. 3 Bar FPR

I have made a number of modifications to my '92 convertible. Red series injectors (30#),APC,Fuel E-Prom chip in the ECU from Swedish Dynamics, and a rising rate fuel pressure regulator from Group 9. I have a lag or a rough spot when I boost from yellow into the red area, usually around 12 - 14 psi boost. I presently max around 17 as I have not set a resistor over ride in the airmass meter. I was wondering if my rising rate fuel regulator was lagging or not functioning properly. Possibly, a delay in fuel delivery. Idleing, it is set at 3 bar. I was thinking of going back to a 3 bar Bosch FPR. Does this make sense? I would just like to have a smoother turbo spool up instead of a rough spot as I do now. Any assistance would be appreciated.
