Seat Leon Cupra 300 Tuning: Flash Your Maps with the NGM App
The Leon Cupra 300 leaves the factory with 300 PS from its 2.0 engine (EA888 Gen3), and that engine has plenty more in it once the software is dialed in. With the NGM App you flash calibrated Stage 1 and Stage 2 maps onto the engine control unit yourself, straight through the OBD2 port: no workshop appointment, no ECU removal, no chip swap. Three variants are covered, the Leon Cupra 300 (2017-2018), the Leon Cupra 300 ST (2017-2020) and the Leon Cupra 300 ST 4WD (2017-2020), each with its own precisely matched file. All power figures on this page are quoted in metric PS.
One thing first: driving with optimized maps is not permitted on public roads. The files are intended solely for use on closed race tracks. The optimization can void your vehicle's type approval and the manufacturer warranty, and you use it at your own risk.
Leon Cupra 300 Stage 1 and Stage 2: What the Numbers Say
All three variants start from 300 PS, yet each one gets its own calibration. The ST 4WD carries slightly different Stage 1 figures than the other two, so here is the full picture:
- Leon Cupra 300 (2.0, 300 PS and 380 Nm stock, 2017-2018): Stage 1 up to 375 PS and 490 Nm, Stage 2 up to 390 PS and 510 Nm
- Leon Cupra 300 ST (2.0, 300 PS and 380 Nm stock, 2017-2020): Stage 1 up to 375 PS and 490 Nm, Stage 2 up to 390 PS and 510 Nm
- Leon Cupra 300 ST 4WD (2.0, 300 PS and 400 Nm stock, 2017-2020): Stage 1 up to 370 PS and 470 Nm, Stage 2 up to 390 PS and 510 Nm
Please note: all maximum power figures were measured with 102 octane fuel and represent the maximum achievable output.
Stage 1 and Stage 2 come bundled in the All-in-One license for the engine control unit. It arrives as a download, bound by VIN to exactly one vehicle, and you flash whichever stage suits your setup directly from the app.
Leon Cupra 300 Pops and Bangs: Sound on Demand
If the added power deserves a louder announcement, the separate Sound license activates the crackles function, pops and bangs, on your Leon Cupra 300. It works whether you run Stage 1, Stage 2 or no performance stage at all, and it is installed through the same NGM OBD Adapter and the same app. Like every NGM license, the Sound license is a download tied to your VIN and to one vehicle only. And just like the performance software, the sound functions belong on closed tracks only.
Tuning Your Leon Cupra 300 Yourself: Four Steps to the Flash
You need no mechanical skills and no appointment, the process is deliberately simple:
- Connect the NGM OBD Adapter to the OBD2 port of your Cupra. The adapter is a one-time purchase and the only hardware required.
- Open the NGM App on your iOS or Android phone and connect it to the adapter.
- The app reads the VIN and automatically detects which of the three Cupra 300 variants it is dealing with.
- Pick your license and start the flash. The file goes straight onto the control unit.
Data for the Leon Cupra 300 is usually available right away. Only if the NGM App has never been used with your vehicle and the data has to be prepared first, this typically takes around 5 days, 14 at most.
