What should i set my fuel pressure at?

[socal200913]

Hey guys! My 87 GN has a K&N intake, walbro fuel pump and hotwire kit, 160 t stat, and a hooker exhaust. I just bought a adjustable fuel pressure regulator from Kirban and I was wondering what I should set the fp at?
Also I will be buying a TurboTweak chip in a week or so. What should i set it at once the chip is installed?
On a side note after putting TT chip in how much did the car performance improve?

 

["Turbo-T"]

Eric recommends setting the f.p. to 43 psi with the hose disconnected from the f.p.r.

What ^ he said.I don't think the chip is any faster BUT gives you more adjustability and that is where the et comes from

Mine is running good at 40 psi so what turbo t said(43psi) would be a good place. I also have a walbro pump.

If you are still running the stock chip the improvement will be like night and day especially at idling.
