Fuel pressure problem!

Hey guys i have an 03 mach with a vortech supercharger in it and my problem is that whenever i give the gas pedal an instant tap orput it to the floor(WOT) it always hits between 70-80psi + on the fuel pressure gauge!!! Is this normal , i would'nt think so...yet at idle everything seems to be fine at around 35 psi. Anyone know what my problem might be?! Any help is greatly appreciated! THANKS!

RE: Fuel pressure problem!

How does the car act when the fuel pressure jumps? Also, what injectors do you have?

Man, you need to get it dynoed ASAP! Trust me, It'll never be right or safe until you do.

Well the car doesnt really act different when the pressure rises,it does however take long for the revs to drop in city driving though when coming to a full stop but i dunno if its related?!...and my injectors i believe are the ones that come with the complete vortech kit. Getting it dynoed was actually one of the first things on the list for spring time but i just wanted to make sure everythingwas fuctioning properly before i do anything.
