Services
Everything to do with your vehicle's electronics and engine. For each service: what we do, and what to have ready for a quick quote.
ECU tuning
ECU tuning adjusts the maps in the engine control unit for more power, more torque or lower fuel consumption. Every file is tailored to your engine.

- Stage 1, with no mechanical changes
- Stage 2, with upgraded parts (intake, intercooler, exhaust)
- Fuel economy tuning
- Reading via OBD or on the bench
- Return to the original software
Good to know. The original file is backed up before any change, so you can go back to the factory settings at any time.
Autotuner and Flex tools
Offer ECU tuning in your own workshop: rent or buy an Autotuner or a Flex linked as a Slave to GK Perf's Master account. You read and write the ECU yourself; we prepare the files and send them to you remotely.

DPF cleaning
A clogged diesel particulate filter (DPF) costs power, turns on warning lights and can put the engine into limp mode. Cleaning often avoids a replacement.

- Particulate filter cleaning
- Forced regeneration with a diagnostic tool
- Function check after the work
Typical signs. DPF or engine warning light on, loss of power, more and more frequent regenerations.
