I have Innovative also, a HP 830 Holley, I was running 13.5 to 12.3 on the track, 1/4 mile, went to Vegas, where there is air, was running fat to what I was running the the year before. The MPH, and ET was much better. Came home to Colorado, changed jets to a fatter set up I ran all last year, picked up MPH and ET. AFR is now a consistent 12.3 to 12.8, and on bad air days within a couple points. This is on 91 pump gas, I have read like you, that it should be leaner. Plugs are clean, burn ring looks great. If I can help out some more let me know. Rick

I just installed an Innovative MTX-L digital air/fuel ratio gauge on LeRoar. I'm wondering what ratio I should be shooting for. I have only had it running in the garage so far and it's a lean 12.9 with stock 750 Eddy. I'm thinking it should be in the 14.7 range.
Can some of you experienced guys chime in here?
