Gauges?
#12
Boost Spikes, Creeps, Exhaust Leaks, and everything else that has to do with the amount of air coming out of the turbo all need to be monitored for.
hence, the presence of a boost gauge in every turbo'd car.
The point being, not running a boost gauge in a turbo car is like not having a tach in a stick car. You can still do it, but you're forcing yourself to guess.

You say you "can't control the weather" but that's exactly what AFPRs and Piggybacks are all about- giving the user control over AFR in boost.

Also, when buying gauges, buy the best you can afford. I bought Megan Racing gauges which ended up being rubbish. The mechanical boost gauge and voltmeter are the only one's that really work. The EGT gauge died a month ago. I'm going for a wideband O2... not sure which brand yet, boost and EGT from Omori next. They're a little more expensive but offer warning options and good quality. I'll probably go with the AEM UEGO wideband kit.

If I had two gauges to choose from it'd be boost and fuel pressure. Beyond that I'd go oil pressure (since the Miata has an ok one already, otherwise this would be first on my list) and a wideband. EGT and narrowband A/F would be last on my list as my experience with them in the past is that they're a novelty.

Think of it this way. The only gauges that are USEFUL are the ones that tell you something is going wrong before something breaks.
oil pressure gauge showing zero means I've already got broken stuff. EGT climbing above 1600 means I can back off before I hose something. Boost rising above my set boost -- same thing. back off. I guess in some ways AFR would tell you if things are going bad too but they're annoying.

Having an AFR display in the cockpit during normal operation may be merely "convenient" but having one during initial tuning is indispensable, particularly if you're using a piggyback or a full ECU. The EMU's A/F Target Autotune, which relies upon a wideband sensor, is particularly handy, even if you're on a dyno.
