I have to get larger chokes and re-jet my 1911cc/dual IDF40s and was thinking of installing a wideband air-fuel gauge to help with tuning. I've looked at a few digital gauges for around $200 that include the gauge, O2 sensor, bung, wiring, etc. Wondering if you guys have any sourcing recommendations and install tips. It looks simple from what I've read. Thanks for any help you can provide.

I removed the velocity stacks and could not tell the difference. I've left them off for now. Today I removed the main jet stacks and drove around. It ran OK if I took it easy up to about 3k rpm then it died. Anytime I put my foot into it it died. AF was around 12.1 at steady state and 1500 rpm. I was running .50 idles so I installed a set of .45s and it still ran good but the AF was 13.5 at 1500 rpm. I think the .45s are good at least for now. Comments? I reinstalled the jet stacks and there was a wide band that hesitated and went lean, AFs at 18-20+. I installed 1.50 mains and it runs strong and most of the hesitation is gone. AF is around 13.0 when easing the throttle wide open in 3rd gear. If I mash it down the AF drops to 10-11 and stays there. I'm not sure what to do from here. So currently I'm running 32mm vent; .45I/150M/2.35A. The accel pumps are reconnected.
