I think you've seen mine
I'm not too sure about that. AutoMeter and especially Stewart Warner have been around for years. Stewart and VDO haven't been around this long by making "incorrect" gauges.I've installed lots of AutoMeter and Stewart Warner gauges and normally recommend people stay away from them.
They are notoriously incorrect and relay bad information.
I highly recommend Greddy or Defi gauges.
Defi actually makes the gauges for Greddy.
Both are very good quality and deliver accurate readings for a decent price.
