I've had a wide band on my truck for about 6 years. I'm using the Innovate LC-1. Once you have this new information, you'll never go back. If you feel a stumble, you can quickly look at the gauge and see 18:1; no wonder. And, like Greg, my truck sees big changes in elevation, and you can jet the carb correctly for where the truck is being used. And when I'm heavy towing, I make darn sure the ratio doesn't get lean under power.

I have an analog gauge with 270 degrees of sweep. I think this displays the information better than digital numbers because we're not talking about a super-steady reading. But being able to see both banks on a v8 would be good too. I might buy one of those for my suburban, as it has the dash hole ready for the gauge (told you I could never go back).

Also consider that with a dual plane intake on a sbc, the carb is *not* feeding the left bank and the right bank separately. So the dual O2 gauge is still a blend of the total carb.
