When I bought my G.N. it came w/a cyberdyne fuel pressure
and boost gauge in the front of the console.
I'm changing them out to Autometers mainly because one of the bars on the fuel pressure gauge started going out intermintinately on me.
What I did notice about them were: they were sometimes hard to read in bright light and also the biggest annoyance was under
acceleration they were difficult to watch because the numbers were changing so fast - looked like the bars on a a slot machine.
