too high static fuel pressure you would need an adjustable regulator to adjust pressure back to normal
i wouldnt install if you didnt install the fpr w/guage at the same time
my $0.02

There are a lot of people running a 255 with stock FPR. It will raise the pressure a bit, but I don't think it's something to be concerned about..

it'll kill your fuel economy a mpg or so and raise your rail pressure a couple points... thats about it. no real harm.
