I already have an EGT, Boost, Oil Pressure, and digital a/f. I'm going to get a fuel pressure gauge and since I've already got a triple pillar pod, I'm considering getting the instrument cluster. So if I do, then I'll need another gauge. So my question is: which would be the best to get? I'd like something that is useful for tuning.

Actually water wouldn't be a bad idea. Our cars rely on water temp to adjust timing and fuel when it wakes up in the morning(or when you start her cold). I would have killed to have a secondary (and acurate) water temp gauge when my water sender to the ECU crapped out and was making my car run rich as hell.
