TCU / GEARBOX TUNING
Our gearbox remapping in Dumbarton tunes the TCU (transmission control unit) on DSG, ZF and Powershift gearboxes for faster shifts, raised torque limits and higher clamping pressure. Pair it with an engine remap or run it standalone — either way your gearbox in Dumbarton will shift with more purpose and less slip.
SuperTune Scotland is based in Glasgow and covers Dumbarton and the Leven valley. We come to the work with a mobile-friendly, file-level approach — reading your original ECU calibration, writing a custom gearbox remap file around your exact vehicle, and verifying it before you drive away. No generic downloads, no cheap emulators, and the original map is always saved.
Whether you're after more power, better economy or a clean emissions solution in Dumbarton, every file we write carries our lifetime guarantee.
Dumbarton guards the gateway to Loch Lomond and the Highlands, so tow cars and high-mileage diesels are common here. Blended Blue Maps and gearbox remaps suit the A82 touring and towing loads that Dumbarton drivers take on regularly.
