What should I run for fuel pressure without going to far? Has anyone played with one of these before? On a 91 hatch with 24lb inj,76mm maf,cai,65mm tb, cam, mild ported gt40 heads, long tubes
 
35-39 psi is a good guesstimate. Each car has its own needs based on the car's parts combination. Remember to set it with the Vacuum off not on.

Go to a track and test-n-tune and see what the car likes!


Don't you have a carb setup?????? then PSI would be a lot less..
 
I got this for my street car its an efi 306. They had it at kragen for 45 on sale. Its the bbk one. Kind of on a halt putting it on now tho cause I ran into other issues. Got a bad vibration when I start the car and also at cruising speeds. Already had to swap driveshafts because there was a section on the old one that had over .020 wear in it. After swapping it the vibration didn't go away tho so I'm thinking something in the transmission possibly.
