Autometer AFR gauge

Who's running a auto meter AFR gauge? They accurate? I read where they are recommended with superchargers.

I ordered a boost gauge and need something else cause the gauge pod I got holds two.

Will be installing on supercharged 2.7l

 

Then with the AFR gauge what one do you get? Three I'm looking at. I know the cheaper one I've gotta buy a sending unit so I'm not worried about the cost just simply what's the best gauge?

 

I researched all the top gauge companies to determine the best deal for the money for an oil pressure and oil temperature gauge.
It came down to Speedhut.
American made, Lifetime warranty, competitive pricing.

Here are there 2-5/16" AFR gauges.
