Just a stab in the dark here, but I was wondering what your hi and low boost settings are set for on your FDs. I'm trying to dial in my boost and I'm just curious what all the settings (gain, boost, etc...) were and the corresponding boost levels that you are making with those settings. I've got my gain set at 35% on high boost and that coupled with 88 on the boost setting, I'm consistantly getting .8 bar. I don't like having my gain maxed at 35%, but I'm not familiar enough with the Profec B Spec 2 to know what a good solid setting to maximize the performance of my T78 would be. I'm trying to set my Hi boost at 18lbs by the way. Thanks for your input ahead of time guys/gals.

My important modifications are:

Streetported motor
T78 kit
Greddy Profec B Spec2
1600 cc secondaries w/ fuel pressure regulator set @ 40lbs and Denso Fuel Pump
Greddy 2 Row 24V FMIC
Magnaflow Resonated Mid-pipe
Greddy SP2 Cat-back
HKS Twin-Power
Apexi - PowerFC

Thanks for the feedback. Have you dynoed your FD with those settings?
