Awesome so far. Only one complaint for the fifth star. Please move the power level switch arrows more towards the middle of the screen and bigger. They’re so small and at the bottom that every time I try to switch the power level I accidentally hit my iPhone window closer bar instead.

I purchased a Quadzilla Adrenaline several years ago and had nothing but problems. It would never connect or disconnect and leave me stuck with half finished tunes on my truck. I ended up returning it and going with an Edge tuner. I recently changed some parts on my truck and the Edge wasn’t capable of handling the changes so I decided to give the Quad another try. Thankfully they seemed to have worked a lot of bugs out. Been using it for several weeks and it hasn’t lost connection once. This tuner truly does give you more control over every aspect of the fueling and timing. That being said you kind of need to know what you are doing. I have a friend who has been working with these since day one and knows them very well and has helped me build a base tune to work with. Hoping I can learn more as I go.

I’ve done hours and days of research looking at tuners and company’s and how to videos to see how the majority of them work and react to my truck(2000 Ram 2500 Cummins). I made my decision and will never change it out. I’ve had my tuner for a while now and never thought I could get this train in stock with 35’s to run as great as it does. No more getting passed by passenger buses and it’s clean no smoke unless you change the settings. Still learning the settings but it’s a great tuner. Been running it for almost a year and love it. I say surprisingly satisfied bec I didn’t think my 7,500lb truck could move as good as it does. Not because of the tuner. The tuner woke it up. Thnx for a great product!

The app has a nice interface and it’s easy to use but the gauges are incomplete. I only have 1 display option and it doesn’t function as it should. Even though I have complete data in data logging the gauges for MPH and ECT are non functional. It’s isn’t as though it doesn’t have the data obviously since it shows up in data logging it knows the readings. I wish they’d update it and atleast provide the option to modify the gauge displays.
