Best fuel pressure

streetstang06 · March 2nd, 2006, 07:34 PM

I've just got my 24# injectors and a fuel pressure regulator. I also have a 75mm throttle body and upper plenum. What is the best fuel pressure i need to run to get maximum power? Thanks

that all depends on the car and what u got in it to get it down on the money u have to take it to get tune imo

why did you go with bigger injectors already?

There is no best, don't mess with the fuel pressure without getting A/F readings. Try sticking around 13:1 at WOT

I've already gone with bigger fuel injectors because i'm over 300hp. I also have cold air intake, underdrive pulley's, jet perfomance chip, low temp. thermostat, 75mm tb and upper plenum, and both tb and intake spacers.
