[DeTomaso] A/F Gauge- wide or narrow?

My experience has been different. I have an AutoMeter narrow band. I'll
admit that I would have purchased an AutoMeter wide band in the ProLite
series had they made them back then; however, they didn't. The narrow band
was a great help to me in diagnosing my carb mixture issues. It clearly
apprised me that I had the wrong size idle bleeds, pump shooter size and
ultimately the jets. I also found it to be consistent with the readings I
got while running a wide band simultaneously in the tail pipe on a Club Dyno
While I am certain there are junk narrow band A/F gauges out there, I have
found the AutoMeter unit to be very helpful. I would not hesitate to
recommend it to anyone. That said, cost no issue - go wide.
