Is it entirely neccessary to have FI to need a boost gauge? Reason why I ask is, don't they measure vaccum to? Would that be important to moniter at all? (As important as volts anyway?)

Okay, I wasn't sure if the big "BOOST" on there and not being able to back that up would be ricey(I might be looking at a nitrous oxide kit later on). I'm looking at the TRD boost gauge with the pillar. I get the idea of psi and everything, but how would "vaccum" be defined in this sense. How much air the engine is sucking in? Thanks again for the replys guys, greatly appreciated

Thanks again for the replys guys, greatly appreciated very good question! alot of guys run boost and dont get the gauges that go negative(vacuam) i like to see the vacuam cause it tells what state the motor is in at or off idle. esp.if a hose or line is off or kinked etc.

vacume when your engine is trying to suck more air then the box can provide such as the moment you ram the throttle the engine is trying to suck air but the Turbo isn't spinning enough yet

A boost gauge on a non-boosted application becomes a Manifold Pressure Gauge. The lower the pressure, the harder your engine is working. If you go up a hill at constant speed/RPM, you should see a drop in manifold pressure.

having it on a non FI engine is pointless really.

yea i would get many other gauges before that ... like i said before get oil or a/f ... a/f is the easyest all you need to do is tap into a wire on your o2 sensor (and power of course) and you get your little lights

Okay so the the A/f ratio gauge is measured as lean/rich etc. right? What's each one mean, and how does the mix. become rich or lean?
