Tuners will tell you that boost is #1, closely followed by EGT. Third is a tie between oil temp and fuel pressure IMO, but after the first two it's kind of a toss up if you're not spending time at the track. I personally still have a set of Defis I've been hanging on to forever- EGT, Oil Pressure, Oil Temp. Someday I may or may not add a boost gauge when I add, like, boost or something. But A/F is not even very useful for tuning, and totally useless when you aren't except for bling factor.
anyway, back to the subject more or less- widebands can compensate for being behind cats, but they lose precision and accuracy to some degree. Doesn't anybody make an uppipe yet with a spare bung for temporary AFR use?
