My fuel pressure gauge is reading 62 PSI at idle. I plan to test that against another gauge but would like to know if the Stillen kit should be idling at 62 PSI or if this way too high.
Any insight would be great appreciated. Stillen's customer service is garbage.

Base fuel pressure should be 51 psi. If you didn’t drill the Venturi in the pump housing the fuel pressure will be higher at idle. I usually leave it this way and adjust for it in the tune. From the factory there are already some significant compensations in place for this area of operation, they simply need to be reworked in the case of higher pressure at idle. If you’re one of my customers just contact me directly and I can review your logs and adjust the tune as need.
