fuel PSI

[phantom09086]

Ok got a 94 gt with 30lbers, whats a good fuel PSI to run them at, I am at 40 with vac line off. I have herd the bigger the injectors the more PSI to make the car run better.

Thanks
Greg

40 psi is fine

is your car tuned for the bigger injectors? does it need the bigger injectors? if not i would assume you need less pressure for the bigger injectors to compensate.

yeah its tuned for bigger injectors, TFS Twisted Wedge heads, b31 cam, pro-m CAI with calibrated MAF,Professional Products Typhoon Intake,75mm Throttle Body.

that would explain why you need the bigger injectors.

yup, i have 30lbers in just wanted to know what a good PSI was for them

Always keep the PSI at the stock 39lb setting. There is no need to up it b/c of mods. Not for street cars anyway
