Air fuel/wideband- pay for a good one that hooks into data logging or tuning sofware(http://www.innovatemotorsports.com) offers some real cool and useable options, i like some of the multi function guages, and wifi/bluetooth/sd data logging to tell you so much more without the hassle of laptop in the car.
Oil pressure guage
Boost psi/vac those three are probably the most useful
