How low have you gone?

[TrrboJeep]

Just currious... for those running adjustable FPR's, what is the lowest pressure you have ran in a fuel injection system? I'm not asking what is recommended here, but what you've actually ran? Has anyone gone below 20psi? Humor me! :eyebrows:

I am below 20! 19 psi w/o the vacuum.:evil:

Ran for long periods at 22, no issues

I may try dipping into the teens to see if I can get her to run/ idle better on initial startup (open loop). She's running richer that Donald Trup for the first 30 seconds or so in open loop, but once it switches to closed loop it settles right down.

+40's = lots-a-fuel..... :nod:

18 PSI static, shouldn't go lower than that the fuel already isn't atomizing very well LOL. But if you ask because of +40's on the stock ECU, you can run 22-25 PSI no problem like Ken ran. Anything over 25 and my car started acting up and running like crap, fouling out plugs too.
