Mercedes C W203 FAQ

Do you have a tune file for the Mercedes C W203?

Yes — for every engine and ECU listed above. Files are built from your own read in WinOLS for your exact software version, not supplied from a generic database.

How do I get a Mercedes C W203 file?

WhatsApp the read to 0466 659 997 with the engine, ECU, your tool and what you want, or upload it at tacfiles.com for an automated return where a matching project exists.

What gains will a Mercedes C W203 Stage 1 give?

Typical Stage 1 figures are shown on each engine card above — measured on our dyno where marked, otherwise the typical gain for that engine class. Final numbers depend on the calibration and hardware, so we confirm per file. Reliability comes first — files stay inside what the engine, injectors and cooling handle comfortably.
