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)

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
