I decided after my non-starting episode that I needed to monitor things under the hood a little more closely, so I'm going to get some gauges for my FD. I have the Pillar gauge pods now...and I'm taking out the passenger air bag an putting the gauges in the housing on a rising actuator system....so my question is, I can fit five gauges, what ones should I get. I already have a column mounted boost gauge.

I was thinking in the gauge pod go with:
1. Air-fuel ratio
2. Fuel Pressure

Then in the air bag go with:
1. Volts
2. EGT
3. ?

 

Read otherwise about A/F, mostly I have heard they can't gauge dick with the stock 02 sensor.

You are missing the most important one by far, the Water Temp.

 

My turbo timer has a volt meter so if it was me, I would go with boost, water temp, oil temp, EGT, and fuel pressure.

 

I have heard that before too. I don't know if its true on the 7 though, but my buddies corrado was that way

 

Well, the A/F gauge will give you a ballpark estimate on where you are at. Granted, as everyone said, it won't be 100% accurate with the stock O2 sensor, but I imagine it would be better than nothing.

As long as you don't use it to tune with, you should be fine.
