hi Todd,

- volt gauge = to check if your charging system works as it should. I had a broken regulator before and fried a couple of components without knowing (charging at 18V instead of 14V).
- afr gauge (air/fuel ratio monitor): this is to protect my full engine rebuild investment. After spending 15K, i don't want to damage the engine by running too lean or something else. After i installed it, it was immediately obvious that my CIS was running like crap...hence the swap to EFI.
cheers, Jan
