      Quality

      Have used the arm uego wideband several times and love it pretty easy to install. This last one though I ended up getting a bad sensor right out of the box I worked for the time I takes to back out of the garage then died. Was a little upset but I got a replacement sensor and everything works just fine.

      AEM AFR gauge.

      People are saying they having lots of problems with these gauges. I learned the hard way. I purchased one a few weeks ago and it went bad on me. It doesn’t read and also the sensor went bad. Do yourself a favor and go with a different brand.

      Decent guage

      Its a decent kit and works but I get some buzzing from it. Looked into it, it seems to be a common problem. They say its feedback into the radio but I had the head unit out of the car and it wasn't coming from the speakers. Haven't tried with the radio in but I've heard its worse. Haven't ran it much but it seems to be reading correctly. I really like you get 2 different color faces and bezels. Was able to somewhat match my other gauges. Plenty of wire and good water tight plugs.

      Fantastic

      This kit is by far the easiest and most accurate way I have ever tuned an engine. It installs easily, works well, and makes determining needed changes to an engines air/fuel ratio a snap. I literally should have bought one of these a long time ago. If you have any carbureted vehicles, this kit is a must. I dialed in my engines tuning in one or two drives, and I would not have been able to make such accurate adjustments without this kit.

      Nice kit

      I was impressed with the quality of the components in every aspect and the really thorough instructions. The wiring was plenty long for sure. I won’t have the engine done for several months so I don’t know about the performance or readout quality, but the AEM brand came highly recommended by an engine builder/tuner. And the price was better than the others that I had been looking at.
