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.

45 psi base pressure. Running 20 to 21 psi boost.

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!
