30-4406 -30-35 PSI Boost Gauge

Awesome

AEM is a well known company in the car world, and makes high quality products. I purchased this gauge to replace a Prosport boost gauge that fried. Installation was painless and took roughly 20 minutes since I reused the air hose from the Prosport gauge. I strongly recommended that you buy an add-a-circuit fuse kit (ASIN B01LFXA5UA) if you don't have any, it will make installation much easier so that the gauge can be powered by one of your car's powered circuits, like the radio. The kit also comes with several butt splices although one would suffice. The cables for the gauge are extremely long, so be aware that you must have adequate room to tuck them away. I paired this gauge with an AEM UEGO Wideband gauge (ASIN B00N3VGPYS) and SMY Dual Gauge Cluster (ASIN B01M7MEKUS). The numbers are also very readable in the day time and stand out in the night, although the sweeping color band is a bit washed out during the day but still visible. No issues with this gauge and I'm very pleased!

I had high expectations given the price point, I liked the fact it had customizable faces as I wanted white specifically. Only complaint is that the boost sensor wire was rather short when compared to their AFR gauge, I installed probably about 2 feet of wire to get the sensor connector from in my engine bay through my passenger firewall grommet and back to my driver side dash. My 07 Vibe is fairly compact so I was shocked the wire wasn’t longer, but it was easily fixable so I had no issue with it. It gives accurate and virtually instant feedback when vacuum/boost pressure changes at all so I’m very pleased with that. Includes a serial and monitoring wire as well if you’ve have another device that requires the sensor feedback which is super handy. Overall I’m very pleased at the price point, they even included multiple ways to integrate the gauge into the boost setup which was convenient. Lastly, it came with very detailed instructions so that was a plus!

I received exactly what I ordered and exactly what I was expecting. I have the AEM UEGO wideband already installed in my 2010 WRX, and I love it, works flawlessly. And since the UEGO has a built-in ambient light sensor, I knew if I got another gauge from a different company, I would not only have my gauges not match, but one would constantly be brighter than the UEGO since it changes automatically. Now, my gauges match and their brightness auto adjust together and it looks awesome

I bought this to mount in my EVO X to watch my boost levels while driving and I am very pleased with the ease of installation and design of this gauge. I also like that they include two different color choices for the boarder of the gauge (black and silver). Installation was easy especially since there are YouTube videos available to show you how to set this up with. All-in-all, the ease of installation, color options, and accuracy makes this a good purchase and I would buy again if need be.

Aem is the best and gave accurate boost readings. Setup was easy did it in my home garage

Had it in my SOLiD Modifications gauge pod In my 2011 STi. Read accurately when compared to the dyno.

Let me start this review by stating that this is indeed a fine boost gauge, very precise, aesthetically pleasing, and comes with a black or white background for you to choose. Installation was easy, although the silicon pipe may come on short on some applications. It has some I/O port for logging, which I haven't used yet, so I will not delve on that. The bad: It is so sensitive that i becames somewhat annoying to see the vacuum change from 20 to 19 to 20 to 19 again and again all the time, when the car is in neutral. It would have been awesome if it had some function to mark max boost. The little green light that does the trick of a gauge needle, needs more illumination. Looks quite bright in the picture here, but in reality you will not see it on bright sunlight, specially if you are going 160 mph on the road. Ah, and no led lightning so if it is too dark, you will see the faint green light but no numbers!! (epic design failure!) For 140 bucks I think you deserve at least better design.
