Auto Meter 3604 Sport-Comp II Mechanical Boost Gauge, 2.3125 in.

After trying 2 of the “Factory Match” Autometer gauges that both had mechanical issues, this one is great. It’s very accurate and the movement is smooth. It measures even a small amount of boost while cruising, where as the other gauges didn’t register till 5 PSI. It’s LED lit from the back, unlike the original Sport-Comp which is lit from the edges. The only issue with this is the LED backlighting is SUPER bright, and doesn’t dim with the truck’s instrument cluster. This must be the nature of the LED they used, a dimmable LED would have been really nice. I’ll be looking into some kind of solution to lower the intensity a bit.
