Welcome aboard Tomas.
Nice first post. You even put your location below your Avatar!
Don't worry about your English; some English speaking members here write it worse than you

It is according t which one you have. If it is boost driven than yes.
If it is just a adjustable fuel pressure riser NOOOOOO!
Basically the pressurer only needs to rise when boost kicks in. That is why the vacume line hooks to it, and the boost drives the fmu to stop the flow of the gas return line, which enturn raises the pressure of fuel to the injectors. Which makes more gas flow through the injectors like they are larger.
So basically if the afpr you have is not boost driven, your pressure needed while in boost will flood your car out of boost. Or if you have it set for out of boost, it will go lean in boost and blow your motor.
The factory greddy has upgradable disk for the fmu.
But if your AFPR is boost driven, that sounds like a better unit.
PS, if you have one of those china afpr's, don't use it. Just get a disk for the fmu.
But if you afpr is a begi, cartech or something namebrand great.
Hope this helps, if you need more clearification just ask.
Good Luck!
