Has anyone tried using one of those aftermarket air/fuel gauges? How accurate are they? From what I understand, they tap into the oxygen sensor and ween their data from that correct? Is that a good way to guesstimate the correct air fuel ratio? Anyone know what the correct ratio would be for the 3.2 v6?
