Does it share files with the Golf?
They share mechanical architecture and ECU families, which broadens our coverage, but files are matched to the specific ECU reference of each car.
Which engine gains most?
The TSI and TFSI petrol turbos deliver the largest outright gains, while the TDI diesels excel at usable everyday torque.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
