So I've been having issues and I wanna monitor the fuel pressure. I'm thinking with the few bolt on upgrades that I might as well get an adjustable fuel pressure regulator with a gauge. Theres more air going into my engine- at least a bigger volume which I trying to get right. But I'm wondering if its worth buying one. I need a fuel gauge anyways, is there any benefit to an adjustable regulator for just a bolt-on modded natural aspiration engine?
I figure its necessary for more extreme mods

 

No. Get the gauge.
