I only have a boost gauge on my evo 8, I know I need air/fuel gauge but what else do I really need? I just want to have the most gauge as I need. I have seen so many evos with single other type gauge with no boost gauge. And many evo with too many guages. Well I am deaf and I can't hear if anything wrong with engine, perhaps gauge will help? So what else do I need for my evo?

 

Wtf is a turbo gauge? You need wideband ,boost and oil pressure

 

when ou say turbo gauge I guess you're talking about a boost gauge, you need:
Boost/Wideband/oil pressure

 

God I have no idea why I typed "turbo"! I meant boost gauge. Yea... I only have boost gauge, boost controller, timer. I have see other evo got oil temp, battery, fuel pressure, etc

 

I only run a boost gauge and air/fuel gauge

 

boost gauge and wideband are great to have. Oil Pressure gauge would be a great addition

 

Personally, I'd go oil temp over oil pressure.

 

Boost and Air/fuel are most important two

 

You want a wideband not an air/fuel gauge.

 

Since you arent avle to hear, you might consider looking into gauges with built-in warning lights. Longacre makes some pretty good looking gauges with programmable lights.

Alternatively you can mount your gauges above the steering wheel with a dual pod so you'll be able to see them in which case warning lights probably won't be necessary.
