iQuad by Quadzilla

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’ve been using quadzilla for the past year! Making tunes, loading them and then trying them. The app works perfectly and the trucks I’ve tuned have such good smoke control and power, best tuner on the market!

Overall the app and module work great, never have any problems connecting or controlling the truck. But since the new iPhones came out, the swipe home feature makes it near impossible to edit gauge format! I always end up swiping home or between apps. Don’t wanna buy a different device when an update could fix this!

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!

There isn’t any sound and you can’t even us the app

2020 update app is useless with original still working Quadzilla Adrenaline. The app worked great for my 99ram but then went away and couldn't re download due to switching iTunes account. Thank you for bringing the app back. So far on my iPhone 6+ seems to be working good.

New update to app is great, tuner is the best out there for a 2nd gen.

Dpg4t is an idiot. This isn’t supposed to support vehicles worldwide it’s strictly for 1998.5-2002 24 valve Cummins powered Dodge trucks with a Quadzilla Adrenaline tuner. And it’s awesome for that.

Doesn’t support vehicles world wide.
