ok so a fpr keeps the fuel line pressure at a set value. but a rising rate fpr is the same thing as an fmu correct? just different terminology.

a fmu or fuel management unit increases the fuel persure as the boost increases where a fpr or a fuel presure ragulator only keeps the amount of fuel presure in the fuel rail at a set psi ,a adjustable fpr just lets you adjust the psi but will not raise the presure past the setting you set it at , where the fmu will raise the fuel presure x times the boost like a 12:1 will raise 12psi per psi of boost 5 psi would be 60psi of fuel presure + your setting of the fpr witch lets say it is at 50psi so at 5 psi of boost your are running 110psi of fuel in your fuel rail and that lets the injectors take more fuel but they will only take as much as the are rated for , hope that helps and if i got some thing wrong please tell me as this is what i was told and what i have read

how so? not trying to be a smartass, just want to know because everywhere ive read an rrfpr and fmu are just two seperate terms for the same device like pop and soda.

no a fmu is much different in the way it functions from a FPR...

I think Bigfoot is blurry, that's the problem. It's not the photographer's fault. Bigfoot is blurry. And that's extra scary to me, because there's a large, out-of-focus monster roaming the countryside.
