  • Gauges and some preset tunes

    By justhtdope72
    So I’ve had the jb4 app and tune in my 2019 Volkswagen jetta s 1.4t 6speed since April. In the beginning all the tunes were there but now for some reason a few are deleted from the app. Also I can’t see a lot of the temp guages. I believe the only one that does work for this car is the water temp. It would be awesome if burger motorsports would do a software update for my car!! There hasn’t been any since I’ve had the app. Other than that tho I absolutely love the jb4 tune and app. It makes such a difference from stock!!
  • Does not work well.

    App constantly cannot see devices, gauges constantly stop working randomly. Since last update cannot connect to tuner no matter how much troubleshooting. For how much this device cost and then to have to pay extra money for the app and then it hardly works (1 year or use…) I’ll be selling this crap tuner. 2019 Raptor.
  • Good when working

  • Problems..Good…But Problems

    By Sandstorm1217
    Have had my Jb4 installed for a couple days now and it’s been a blast. The problems lie mostly in the app. Most, as in 90% of the display options such as rpm, gear, speed, etc. have not worked for me. But, things like boost, gps speed, ecu boost, oil temp, etc. have worked but will stop after a certain amount of time. Customization is great, but the graphs don’t work even after doing a log. Have a check engine light on, probably from my high flow cat for my F30. But, the app says I have no codes showing up so I can delete them. Watched every how to vid and no one is addressing my problems..maybe this needs another patch
  • Great customer service

  • Can’t connect to server

    By n54 dude

  • No CarPlay??? Seriously?

    By ryanovelo
    I spend $600 on the JB4 and another $28 on this app and I have to keep my phone out to see the gauges. Insane. Despite that, app works great. CarPlay is a no brained addition.
  • Great app
