What is the difference are they two totally different setups? Like a 12:1 FMU is basically the same thing as setting the PSI of the fuel flowing through the rails on an adjustable fuel pressure regulator? Is there a chart for the different fuel pressures. or do you just tune it off of your wideband I'm confused would appreciate help guys thanks
can you run both?

Re: Fuel management unit / Adjustable fuel pressure regulato
Lulz, are you boosting your car?? I don't see it going well if you use this method.
But ya u need a fmu and fpr. Fpr regulates fuel pressure going in (as u would have more then stock under boost) and the fmu regulates the amount going in based on each psi of positive vacuum, aka boost.
