I run an Autometer Sport-Comp 2" mechanical FP gauge.  I know that you are
looking at electric FP gauges, but if you want a fast response, I recommend
mechanical.  Once you get past the fuel pressure isolator (bleeding it is a
PITA) it works fine.  BTW, I have seen my fuel pressure ramp up to 95-100psi at
5800rpm and 6psi boost.
