need some advise from tuning gurus , i've got 3 gauge pod with boost and wideband installed already , want to add 3rd gauge but can not decide which one i need more. car is used for time attacks and autox sometimes .

want to choose between EGT , oil press or oil temp . what do you think?

 

EGT & Wideband are actually required by some tuners. EGT is more important than oil pressure/temp in my opinion. It changes more, and can affect a lot of stuff, and if you drive aggressively for a somewhat extended period of time it can definitely save you from ending up on the side of the road (wish I had one when I overheated my exhaust, turned the turbo red, and blew a coupler)
