Adjustable fuel pressure regulator
 

Any body put one of these babies in and tried it? I'd like to just up mine a few psi.

First of all I wonder why?

Secondly, your engine uses a fuel rail pressure sensor to control fuel pressure to the injectors, modulating the fuel pump output with current control. Even if you put an adjustable regulator on it, the PCM will control the fuel pump to the PSI it determines to be correct.

That's why I'm asking. I don't know all the controls that are in place. I guess it's time to buy a tuner and modify with it. A little more pulse width goes a long way.
