Don't forget when buying this you also have to buy a boost bolt. If your driving a dodge cummins. Glow shift makes one that works great.

Purchased this and two others. Trans temp and EGT. These factory match gauges look and work great. I would recommend them to anyone else who runs a Dodge/Cummins.

Does not match 2003 or 2004.5 Dodge Ram gauges, close but not quite. The numbers are incorrect in style.

This didn't come with wire to wire it. Other then that, the gauge looks well made and matches factory look really good

Does not work as a vacuum gauge although autometer told me it would.

First one was defective. The needle stuck in certain spots and only read to 28 psi. The next one was nice and smooth and read the full 53 psi that my wastegate is set for. The only thing that I don't like is that it doesn't dim with cluster even though it is wired in with the dimmer switch.

Bought 3 new gauges off Amazon everyone of them lights up but the gauge itself doesn’t work, poor quality

Factory matches pretty good. Gauge doesn’t come with a wiring kit though so I made my own. Also the 1/4 npt port is an odd size as usually they are 1/8 npt so now I have to find an adapter for it to work.
