I am looking get get gauges for my STi and was wondering which ones are the most important to get since I will be modding my car and even slightly increasing boost.

I know a boost gauge is one of them, but not sure what else do i need.
EGT? Fuel Press?

I know this question shouldn't be trivial but with my experience I've found each car is different.

In my turbo civic, all I needed was a boost gauge and an A/R gauge.
On my 3000GT VR-4 I needed a boost gauge, A/R, and two EGT's.
