With my stage 1 you can get around 155 hp and 270 Nm of torque. Message me on WhatsApp, since I can't write my number here: +39 3517678137

Here is the Stage 1 file I have for the same ECU. Could you please compare it with your file and let me know the differences?

ECU: Bosch MED17.5.53
Part number: 03C906016AP
Software: 517819 / 9086
Vehicle: 2012 Seat Leon 1.4 TSI

My file was extracted from a WinOLS project and contains the 256 KB calibration area. Please check the tuning changes, maps, and checksum before using it.

If you find it helpful, please don’t forget to leave a like and say thanks.

Does file stage 1 have the same hardware and software as your original ECU? I can't check the file, but I can perform a stage 1 on your original file so I can be sure of everything and send you the graph with torque and horsepower.
