#935, "RE: How does the stock FPR interact with the FMU to come up with whatever fuel pressure it does?" In response to In response to 2
Here's the deal with the SFMU... You can keep using your stock fpr if you wish.. or you can toss it because the SFMU allows you to regulate idle fuel pressure. So it acts as a fpr/fmu.. But if you want to use the Stock fpr you can still use the sfmu by putting it inline to the fpr just as you would with a regular fmu..Only thing is now you cant "lower" your fuel pressure below stock.. You can only raise the idle fuel pressure..
