Fuel Pressure Question...
I need to set my fuel pressure on my 86 now that I have a Holley AFPR and abrand new set ofFord MotorSport 24# injectors. What should I set the pressure at so my engine does not run too rich? I have a custom chip done by Ski_dwn_it also, along with a magnaflow catback, random tech cat, and hooker 2149 headers and a hooker y pipe. Not sure if any of these mods make much difference but I thought I would list them anyways. I also have a smog pump system bypassed. Thanks!

I've got an 86 with about the same mods plus a cam. I know you can go a lot higher, but mine seems to run best set at 40 PSI (at idle with vacuum disconnected).

That's not much at all. With the vacuum line connected it would be in the very low 30's.
