you wanna be a little more specific?

Your stock FPR is not gonna raise fuel pressure like an FMU

An FMU is used in conjunction with the stock FPR

The Vortech SFMU however requires the removal of the stock FPR

One is Fuel pressure regulator,

other is Fuel Management Unit. Allows for adjustment of boost/fuel ratio via different disks/diaphragm.

In theory they work the same way. However, FMU can raise fuel pressure upon boost.

SFMU allows for adjustment of different ratios via disk/diaphragm, plus adjustment of idle pressure.

Hope this helps.
