Which 6 Gauges would be THE most important to have in a Turbo Forced induction set up? I love gauges! I know that at least 2 are pretty much standadrd/very important, listed blelow in order of importance. I know auto meter makes some cool gauges like the D-pic which is a data gauge (Quarter mile times, reaction times, real time g-forces, etc) pretty cool but not 100% necessary, same thing with shiftlights, cool but not 100% necessary.

1) Wideband Air fuel ratio
2) Boost/Vac.
3) ?? Fuel Pressure??
4) ??Water Temp??
5) ??Oil Temp??
6) ??Transmission Temp??

THANKS!
