I recently installed a Kirban AFPR (thanks Ben) and I am running about 42psi base fuel pressure (vac line disconnected). I noticed a nice change in performance. Acceleration feels smoother, and the car pulls a little harder under boost. I can feel the change the most at max boost (~18psi)- It used to have an almost imperceptible feel of hesitation, and the little bit of extra fuel pressure seems to make all the difference.

I don't yet have the Walbro 255 pump, but I know the Kirban made an improvement.

Excuse me if this has already been answered, but where's the best place to buy the Kirban AFPR, and which one? I don't see any TC specific on their web site. Thanks!
