In regards to FE instrumentation, on a usefulness scale from 0 to 10, considering a scangauge being 10, how would you rate a combination of a/f ratio meter, closed loop monitor and vacuum gauge?
Narrowband AFR meters are completely worthless.

Wideband AFR meters are highly valuable if you know how to interpret and manipulate the output.

For a fuel meter, I'd rate the SG at a 7. The other things you mentioned, the SG already does, so there's not much need for discrete components.
