What's the most accurate way to measure A/F numbers? Would using sniffers in the tailpipe be enough?
Most accurate method is a direct AF sensor plumbed into the exhaust stream before any cats.

Tailpipe sniffers vary in accuracy, based on the method and dyno, but the good ones are fairly accurate, and certainly accurate enough to determine if you are running dangerously lean.
