Review on AEM 30-4406 Boost Gauge: Reliable -30-35 PSI Measurement with Precision by Nick Reddy

Installation is easy and the presence of an electric gauge allows for very short vacuum lines. The sensor wires are long enough to run from the driver's side to the aisle side and into the center of the engine compartment before connecting vacuum lines. Very, very responsive. Cons: The included tee is small and crappy, I recommend just throwing it away. Vacuum is no different from overpressure. At idle I read 20, under load it counts to 0 and then ramps up to 11. I want the vacuum to have a negative sign or change color when it's below 0. The sensor mount is big and heavy, so you'll need to attach it firmly to avoid breaking it. and causes a boost leak. The kit should include a mounting bracket for the sensor.
