I Want A Refund

This app does NOT work on the iPhone 12. The jb4 doesn’t even show up in my Bluetooth list. I keep getting an error message saying the pin is invalid but it doesn’t even give the option to input the pin (I know my pin). If you have the new iPhone it’s not worth it. I’m requesting my money back from Apple support smh Gonna get a data cable instead!

4 star for now!

App is easy to use but it will be more useful if it have car play compatibility!!! Having all that info in ours car infotainment and make changes on the fly whit out touching the phone will be fantastic!!!! Other than that i love it!

Great and fast Customer service.

I had the opportunity to resolve connectivity issues on two separate occasions. Both times customer service not only responded quickly but also addressed my concerns very fast. Two thumbs up to Miles Woodrum.

Had a good response time from the team with the small issue I had. Hope I can help test out any new features you will offer for the q50.

I’m in love with the jb4 and having a blast on map 2. It’s a huge difference from stock. Customer service has been fantastic as well. App is very easy to navigate through. Would definitely recommend going through them.

Worth the money!

Everyone at JB4 has been extremely helpful and quick to respond. Never had a aftermarket tuning company respond so quickly. You can tell they value every customer! Would 100% recommend if they have tuning for your platform!

New Stinger User Suggestion

So far I really like the app and the JB4. The app connects quickly via Bluetooth and I haven’t had one issue after a week of use. Something I’d like to see is multiple gauge screens to scroll through, similar to the Ultra Gauge app if anyone is familiar. That way, my most used gauges are on the first page and gauges I reference less like map, temps and waste gate data could be easily accessed by a swipe rather than having to temporarily reset a more utilized gauge.

App is great

App is great but greatest is the customer service, I’ll keep an App or a business near just because of that!
