I'd say that you're spot on target, Richard. Most of the kids running nitrous just believe the jet to spray ratio that comes with the kit, which I expect is biased rich to limit what little liability the kit guy might have. Seems to me an A/F meter would be a necessary accessory to get the hardware dialed in right.
