Has anyone on here used a A/F meter when tuning a t-quad



Only since the early 90's!

O2 sensor and gauges takes a lot of guesswork out of tuning and the gauges are certainly cheaper than 20 years ago.

Some folks will state you need a wide-band sensor for proper tuning, this just isn't so unless you are on the ragged edge at WOT in my honest opinion.

I have tuned engines running 30 psi on gas with narrow band factory sensors without fail, now that can get hairy fast if you screw up.
