I'm pretty sure that's a RISING RATE FPR...
Those things should NOT be used on a properly set up fuel system.
It should only be used on hack turbo-on-NA on stock ECU's...like those turbo'd Hondas.
If it is a RRFPR, it's not surprising to see 80psi.
I've seen ratios as high as 12:1.
Throw that thing away, and get a proper boost-dependent FPR which is a 1:1 ratio.
I prefer SX FPR's myself.
