Remote ECU tune · M133 2.0T
A custom Stage 1, 2 or 3 calibration for your Mercedes-AMG CLA45 (C117), built by hand by a real tuner from your own stock file and datalog, and back with you within three hours of the file arriving. We tune these cars remotely, worldwide: you read and flash with your own HP Tuners interface, and you pay only once the tune is delivered.
Specialty platform. The Mercedes-AMG CLA45 (C117) is one of our specialty platforms: our tuners work from a dedicated, in-depth calibration recipe written for the M133 2.0T and its Bosch MED17.7.2, rather than general platform guidance.
Stock vs tuned
From the factory the Mercedes-AMG CLA45 (C117) makes 355 hp and 332 lb-ft (450 Nm). A Stage 1 tune typically adds 50–75 hp and 59–85 lb-ft, for around 405–430 hp in total. With bolt-ons and a Stage 2 calibration that grows to +80–105 hp, and a Stage 3 build — a hybrid or upgraded turbocharger, with the fuelling to support it — typically lands at 455–505 hp.
