What information/gauges are necessary to monitor the health and performance of a supercharger. Can OBD-II data be used instead of extra gauges?

Here is what I plan on buying:

Fuel Pressure Gauge
Boost/Vacuum Gauge

Thanks

Think I'm going to go with a Wideband A/F ratio gauge as well. Might help with tuning a bit. And I'll have real time running lean or rich.

 

The two you have listed are the most important.

 

i'm running boost,a/f,and haven't decided to put either a oil temp or exhaust gas temp. gauge in my 3rd pod....
i have both gauges, just need to make up my mind..leaning more towards the egt.

 

Fuel Pressure & Boost are usual....

optional - AFR

for a lot of track, differential fluid temp...
