I'd get a boost gauge if you're still running the factory one. Not accurate enough if you start to mod.

Water and oil temp I think you can do without (unless you plan to track it), others may feel differently. If its not overheating you are fine, and the OEM gauge will tell you just as well as any other gauge will.

All I ran in my car was boost, AFR and oil pressure. Everything else was OEM.

Edit: realized this is for a GT-S but I feel like the info is still solid

boost

Forgot to add that, I've got an aftermarket boost gauge already. Which brands would you recommend? Not looking to spend the money for Defi.

a good boost gauge. oil temp and pressure are a must, A/F ratio is good to have

edit: i have boost, oil pressure, fuel pressure, water temp, exhaust temp, oil temp and A/F. all are autometer accept the A/F is AEM

Boost gauge (if boosting above 13.5 psi, which is max of stock boost gauge or basically +7).

Oil temp gauge (used to determine oil to run, see if oil is overheating on racetrack)
Oil pressure gauge (used to determine oil to run and monitor wear of bearings, etc)
Exhaust temp gauge (used for tuning engine)
Coolant temp gauge (more for track where you need to monitor coolant temps)

If was me, I would run HKS camp (takes up less room than gauges and cheaper than a set of gauges, have more options as far as digital gauges go) -

Or run Greedy Informeter Touch with additional sensor options for oil temp, oil pressure, etc (takes up less room) -
