buy an A/F guage, put in an O2 sensor and forget about "guessing" what it wants
maybe santa claus is listening. 
Forget the A/F meter on a race car... you know to tune
for the fastest MPH... then if you want you can take
a A/F reading... there is no magic number to tune to
If I were to do anything I think I would concider a pyrometer and tune by egt, but untill then I am going to tune by coolant temp rise and like you said,,MPH, if I were running the snot out of it every weekend then I may be more enclined to get into the o2 and A/F sensors and such, but that just not in the budget at this time. 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

Bill...when you get it tuned in for best MPH you
will most likely see a 20 degree temp increase in
the 1/4

Mr P most of the tuning i have done with an O2 watching H2O temp shows 8-12* to be the right tune. On the combos I have logged O2 on this puts lambda at .80-.82 which is where you want to be for a quick consistent tune.
What temp do you leave at... I think I was leaving
a bit too cold... I should have been near 180-185

Most cars like 170. I have run mine as low 160 and high as 180 with no real performance change.
Normal runs in the heat of summer leave 170 go through a tick above 180. In the spring and call leave at 170 go through a tick below 180.
Thats why I said 20* increase... I was leaving at 160*
and seen 180* at the end.. most of the E-85 guys I've
talked with found that they made more power leaving
at a 180* temp... some even at 185*... I never tried
the higher temps myself but plan on trying it

I'm usually doing my burnout without the fan off to bring it up to 165ish. I've never seen an increase in power running hotter or colder than that.

Been tuning cars by the seat of my pants for 30 years. works just fine 
I have all of the fancy dandle stuff but I use it about
10% of the time... my A/F meter is used for cruise
A/F only.. I tune the race car on the MPH... I never
seen the need for it on the race car... I set the idle
for where it idles best and WOT on the MPG
