Going AFR gauge & O2 sensors 
Bob I'm just curious, If you don't mind me asking
what did it cost ?
who'd you get it thru ?
what brand is that ?
is it open loop ?
or closed loop ?
do you have any way of recording/data logging etc.
what it actually does throughout the rpm ranges ?
(I'm thinking about doing it on my street-beast too
the altitudes/elevation changes up here really play havoc on mine
I plan to go to a custom application FiTec EFI 6bbl probably too)
for a drag car WOT
or on the chip/converter etc. is the most important
like AFR 12.4 to 12.8 WOT is safe & makes decent power
13.1 is starting to push it (lean side)
staggered jetting helps (or can) some too,
get a good plug reading
usually the rear plugs sometimes 7 or 8 cylinders are rich
some the 1 &/or 2 cylinders are lean/er
(but pulling fuel away from the back will fatten them up sometimes too)
Engine Masters
episode 5/21
Tunnel-ram vs Cross-ram
Ignore the title, or the engine they used (SBC)
they start out with a single 4bbl (dual plan)
it's a good lesson on staggered jetting, cause & effects
great examples of what helps where
anyway
good luck, it should/will help, you'll do well

Got it from summit racing for about 315 bucks.
It can record to a laptop.
Has a real time gauge which I mounted right in my face.
They have a program you can download for free on their website.
Some people have had problems with them on the street.
But I'm just looking for WOT.
The people I heard from with issues were all carbureted cars.

Holes? Oh man. It's worse than we thought? Perhaps variable timing for multiple bung holes?

There were better options out there. I'd return it. I had the lm2. Nothing but problems. Connection problems when I needed the information the most.
Return it and get something better if you plan on keeping this crazy hobby.
Spend a little more now or a lot more later.
Just a suggestion.

Are you willing to offer a suggested "better" alternative to go along with this critique?
