How much is too much?

[LaserSVT]

Hey there boys and girls! Could anyone give me an approximate on where I should start with my fuel pressure setting with the mods I have? I dont know what pump size I have but the rest of the mods are on the bottom.

Without dyno testing, you're really not going to know for sure, but I'd start at about 39lbs as a base line and if it runs well, leave it there.

^yep

Start at the stock psi level and only adjust if it is needed.
It can be hard to know without a WB O2 though...


good luck,
