an in cockpit fuel pressure gauge is kind of dangerous, i know its illegal at the dragstrip here...
i went with boost (of course) and EGT because a/f ratio gauges are off, and i also didnt go with autometer gauges, i went with apexi because japanese gauges are a bit more accurate...

yes but underhood gauge is half useless unless you have a dyno. the most important measurement is peak fuel pressure, and that only occurs at full boost. hard to look under the hood in those circumstances.

the a/f is fine as a rough tuning tool. i don't really advocate doing any tuning on the JRSC at all, except for having the fuel pressure adjusted after seeing a wideband A/F plot. all the gauges in the world would be great, but it will tempt you to screw around, especially if you believe them to be very accurate.
i think they're more useful for disaster prevention than tuning. spend the $$ and get the in-cockpit A/F, and a boost gauge. you just bought a JRSC, a hundred or two hundred bucks is cheap insurance.
if, for example, your fuel pump was failing, or you had a small leak anywhere (at 100+psi that's not too terribly unlikely), or your FMU was crapping out (has happened to a lot of people) the in-cockpit gauge will save your motor. you'll see the pressure drop.

once again, i don't think the b&m gauge is a good idea on these cars... he only had his on until he got the sender and in-cockpit gauge.

scwhett...think you can do me a fovor and take a pic of the fuel filter with the jrsc on? they say you can see the preassure when its there

I have a boost, electrical full sweep fuel pressure and the J&S monitor. I found those to be useful enough to detect if something is going wrong. Just dont use the gauges to tune, but to rather make sure your car is running good and safe all the time.
What's the use of an A/F in the cockpit? Boost and fuel pressure are the most important if you were to pick 2 out of the 3. You won't want to tune with the cockpit a/f gauge, you'll want to use the wideband for that. I have the electrical fuel p gauge, yes it's $$ but no one ever said going FI was cheap.
why don't you wait until you have everything you want and do it right the first time...unless you eventually want to rebuild your motor, it's prudent to have the appropriate anti-detonation devices and monitors in hand especially for the boost fragile H22s.
