    Digital Vent Boost Gauge. Carefully monitor your force inducted 2015-2020 Mustangs boost/vacuum by installing a Raxiom Vent Integrated Boost Gauge. This simple digital Boost Gauge gives you the ability to observe your boost pressure to assure that your Pony is running at its peak performance. Pre-installed in a genuine Ford vent housing, the Raxiom Boost Gauge installs directly into your dashes HVAC vent for a clean sleek integrated appearance. This Gauge does not interfere with the operation of your Mustang's HVAC system.

    Boost / Vacuum Pressure. Raxiom engineered their Boost Gauge to monitor your Mustang's boost and vacuum pressure in real time. Using the supplied 45 PSI high resolution boost sensor this Gauge will accurately measure your Mustang's manifold, turbocharger or supercharger boost pressure. By tapping into a boost/vacuum line the Raxiom Boost Gauge will provide more precise readings than those taking from the OBDII port (PCM).

    Battery Voltage. The Raxiom Vent Integrated Boost Gauge not only monitors your Mustangs Boost and Vacuum, it also monitors your battery voltage as well. Raxiom's Boost Gauge allows you to easily check your battery voltage with just a push of a button. This is a great feature for Mustangs that are stored for long periods of time.

    Auto or Manual Dimmer. Raxiom designed their Boost Gauge so that it can be dimmed automatically in conjunction with your interior lights or manually with a push of a button. This is a really nice feature that further enhances its function and sleek appearance.

    Recommended Upgrade. If you find that the supplied vacuum line included with this Boost Gauge is too short for your needs, you will be glad to hear that Raxiom offers a 60" (5ft) Extension Kit. AmericanMuscle recommends purchasing the Extension Kit at the same time to avoid any installation headaches. Sold separately, see option listed above.

    Application. The Raxiom Vent Integrated Boost Gauge with Housing is perfect for any supercharged or turbocharged 2015 to 2020 Mustangs, including the V6, EcoBoost, GT and Shelby GT530 models. The Boost Gauge arrives pre-installed in a factory vent housing.

            The product looks really good. The installation instructions are not completely terrible if your a decent mechanic and good with wiring. The vampire taps that comes with the kit do not fit the wiring to the connector so you must use the longer extension wiring that comes with the kit. There are no instructions at all for tapping the vacuum source so I did my own investigation with testing a true vacuum source with a vacuum meter. The only place you can actually guarantee a proper vacuum is by purchasing a hose barb and putting into the lower intake on the passenger side, then connecting the Vacuum line to it., This all sounds easy enough and it would have been if the instructions were there and the product actually worked. As far as functionality goes the unit is working but it isn't working correctly. It should read vacuum as negative numbers and boost as positive numbers. The way it is actually working is that a vacuum of 15 is actually read on the Raxiom gauge as -4.5, zero vacuum is actually read as 6.5. Boost works correctly starting with 6.5 being the no boost point, so full boost actually shows 14.5. All in all I have spent many hours switching things, trying different hoses etc and invested a full 6 hours of time trying to make this unit work. I would recommend not wasting your time.

            Poor Instructions

            The first one had a faulty harness and was returned without issue from AM. I purchased a second one that has been installed but does not show boost. I intend to return it as soon as AM sends me a RMA and label. The Raxion instructions are very poor when it comes to configuring the parameters with little discription. Finally, Raxion does not have any accessible tech support. AM tried to help me with it but had the same poor instructions that I did
