Would you want to blow an engine because something in the fuel system isn't working and you didn't spend and extra $100 or so and a FP guage?

I vote for yes......
EGT can't tell you everything...my aux pump was off few months ago and all I can see is the EGT gets hot very fast. If I have a FP gauge....I will see the FP at WOT will drop if the aux pump is off.
fuel pressure at WOT = a * b + c/2
a = your boost pressure
b = your FMU ratio, 8 if your FMU is 8:1
c = FP at idle.
you have to monitor both air pressure and fuel pressue for a turbo car.
