After months of having this boost gauge installed I have had no failure to read boost what so ever despite going through 6+ autocross events and 80+ degrees of hot weather, this is by far the best boost gauge I have ever bought well worth the money

Tough Install but worth it

Was a pain to get installed, but it's nice to see boost on the a-pillar. I still have to hook up the RPM wire, I'll do that before it gets cold. Reads accurately, plus it looks good.

Great gauge!

This is a great gauge in combination with the AFR gauge. BE AWARE! this gauge measures ABSOLUTE pressure and not relative. I live at 9000' and because of that the gauge shows 9 low when in vacuum and 6 low when in boost. I can't wait to use it at sea level. Innovate said there is nothing that can be done about that.

If you are using a gauge without a solenoid to recognize your boost I would highly recommend this gauge. The install is quite simple. Mine is not plumbed into the tach wiring as I only wanted a boost vacuum reading from the unit. Due to the signal from the pressure source only traveling a few inches as opposed to a few feet the reading is more accurate. The face is easy to read day or night. My only complaint (hardly a complaint) is the sensitivity. I feel the increments should have been to .5 psi. It gets hard to juggle the small changes while doing a pull on the freeway or what have you. This may be fixed with some programming and I'm speaking of the default settings only. Buy one... And then... Buy the matching AFR gauge. Money well spent

Looks great and very accurate

Pros: 1. Installation was a snap with great instructions. 2. Bright LED display and shift light even during the day. 3. LEDs are not blinding at night like other gauges. Even being yellow it still leaves great visbility at night. 4. Configuration of the shift light was easy as long as you can find a tach cable from the ECU. Cons: None.

    Geoffrey said this gauge displays absolute pressure. Is this true? so when the car is not running it will be reading pressure?

    • A: Hi Geoffrey, Cort from Innovate Motorsports. The MTX-D Boost reads gauge pressure, not absolute. You do have the ability to use the altitude compensation feature by using our LM Programmer software. Program cable is included with all our kits.

    Can we see a pic of how it illuminates at night?

    • A: We will post up a photo of it at night as soon as we get one. Right now Innovate does not have one for us.
