So should I leave it at 60?
Does your fuel pressure fluctuate with the Fuelab pump. I have it set @ 65psi, but it ranges from 60 - 70psi depending on when I look at it.

I only have the mechanical gauge under hood. Seems like when I start the truck, fuel pressure is about 60psi. When the truck has been driven alot, pressure is around 60-70. IDK???

60psi is good. Anything above 70psi, my truck seems to take longer to start.

I dropped mine down to 55psi and I picked up a few HP on the dyno. Not sure why.

Stock injectors I ran 70-72, stage 2's were at about 65 and hybrids at 60...

Every truck, every injector is differant.
