TDI Tuning

real difference to the drivability of my truck.

Edit 09/11: App updated Nov 2025. STILL CONTINUES TO FAIL TO CONNECT VIA BLUETOOTH. Yet I have no issues connecting to any other devices. Still 💩💩👎👎🤡🤡. New Google Pixel 8 phone. Continually fails to connect via Bluetooth. Yet, older Pixel 5 has no issues. No app updates since 2022 which is nearly 1 year before the Pixel 8 was released. Customer service is USELESS. VERY POOR.

can't connect to Bluetooth

(MY CAR : 2024 HYUNDAI SANTA CRUZ) my experience: i got the app for the tdi tuning box & once installed i noticed a good difference in power, i drove the car about 300km with the box until my engine started rattling like crazy & idling horribly. & then a orange check engine ( cyl 2 miss fire ) . i took the box off, NO engine rattle at speeds, but i still got a very rough idle, now who knows the damages there cheap product has caused my DAILY vehicle. STAY AWAY.

As with most of the reviews, the app doesn't work well due to poor Bluetooth connectivity issues. Pretty poor for a premium product

The app works with Samsung S21 One UI 7.0, Android 15. GPS must be turned on along with Bluetooth. If GPS is off the app won't connect.

Nice app for remote operation. Activate location to connect for first time to tuning device with Bluetooth. After that it easily connects using Bluetooth from inside the car. No issues.

Phone keeps dropping connection, you pay extra for the Bluetooth version and you can't use it as a Bluetooth device
