boost wideband oil pressure and egt if you want it. def boost and wideband first esp with your mods.

to above poster: you are right oil is monitored and not easily adjustable. however, unlike most cars, the evo does not have an oil pressure gauge stock. so yes, it is a extra safety mechanism. i have seen an oil leak right after a change. luckily, saw the oil on the ground before any damage was done. but had there been a oil pressure gauge, would have seen that pressure wasnt building and immediately killed the ignition. that engine almost seized up and went bye bye. its all about preference, mods, and what you will be doing with the car.

 

Will I looking into upgrading my gauges to Defi, Thanks for the input

 

EGT, oil pressure, boost, AFR

 

I personally would pick a wideband over an EGT. Otherwise I'd go with a wideband, oil pressure, and boost.

 

EGT's can tell you just as much as a wideband

 

Anyone know of a good boost oil pressure and wideband that light up red? And easy on the wallet haha (Brand and model)
I want to kinda make it look stock post some pictures up! thanks guys

 

Oil pressure is just an added security gauge to let you know if the motor is running correctly. all i have is boost and oil pressure for now. looking for wideband o2 i future hope soon

 

auto meter gauges are reliable

 

Yo anyone ever used an xtd ebay clutch please write me thanks

 

That's the same setup I have!

 

Are you telling me that an EGT can tell me the exact AFR that I am running like a wideband???

I say boost, afr, EGT, and oil pressure are the ones you really need. Fuel pressure could help too.

 

Volts - #1 gauge

 

Egt is a little trickier to tune with is it not?

 

wideband, boost, oil pressure

 

None! But I have a boost gauge, my wideband is wired directly to my ecu for logging only.
