A/F guage that displays voltage
http://www.2gnt.com/www/corbin/dvm2.html
You can make your own A/F guage that reads like a voltmeter instead of one that uses LED bars. Probably a lot more accurate for tuning your A/F with a turbo.
What you could do is build one of these and use it combination with a Dawes A/F. That would be trick and would have great dual purpose use. A/F at a glance or A/F for fine tuning.

Well in my eyes the Dawes is good enough, but with the voltage A/F too you can tell when you are starting to run out of fuel easier. Like say for example you are sunning a Dawes and you are green lighting at WOT (assuming green is stoich on a Dawes), this doesn't really tell you exactly where you are in that safety range, you could be sitting at the edge. Then say you turn up the boost some and your Dawes A/F starts lighting the lean LED at WOT. If you had a voltage A/F then you would have known before you even attempted to add some boost that you were going to need more fuel than you have.
You could use a normal A/F LED display besides a Dawes but most of them have LED's out the yin yang. Like my Autometer A/F, it has at least 20 LED's, there is no way I would try and count them while driving. I just look to see what color is lit and I can also tell wher my A/F is relatively.
And yes Jeff we were talking about this the other day, sort of. Actually we were talkign about your dash and where you mounted all the guages, and you said you used the Dawes at a glance and had another one for more precise tuning.

Also just using either 4 or 5 leds you can mount them directky in the dash for a stealthier look. Or just mount that LCD display in the dash. or on top and have it show up on the window like a HUD. I seen another one where you can use leds to indicat when an extra injector turns on at a diff voltage and will also tell you where you're AF is at. That way it automatically compensates.

Hell even better idea, make that extra injector controller and the numeric A/F guage onto one board. Then you won't even need another A/F
