which is more useful for my fd?

I think definately an EGT. Or if you don't have one a regular aftermarket temp gauge. Depends on what set up you have but the minimum requirement generally is the temp gauges first and boost. A/F just usually sounds more "tuned" to have on your list of goodies, than useful.

a/f ratio gauge is usless, get a egt, actually dont get that, get a water temp/oil temp/oilpressure/fuel pressure gauge before both of those

Get a wideband A/F gauge.

agreed......but depeneding on your mods this would be a little extreme. If you are still pretty much stock then spend your money else were.

Dual EGT gauges and dual widebands for each rotor!

Yeah, 'cuz the temperature wouldn't destroy those widebands instantly :-\

I didn't say mount it 3" away from the exhaust port.

LMFAO.

My tech edge Wideband is still running strong.

Same with my FJO

But AF, and EGT, won't tell you much, especially if you have the stock sensor... either get a wideband setup.. AEM Makes a nice gauge/meter setup, or get something that's going to tell you when things get dicey like a Radiator Water Temp Gauge Mounted into the water pump houseing so you get Temp before the Thrmostat opens...
