How it works

Simple process, no drama.

  1. Enquiry — tell us your car, ECU/TCU, mods, fuel, goals.
  2. Health check — scan + key logs so we’re not tuning problems.
  3. Calibration — off-the-shelf or custom, depending on your setup.
  4. Verification — road test/log review, tweaks if needed.
  5. Aftercare — advice + optional follow-up logging.
Trust

What you can expect

  • Clear comms and realistic outcomes (no Facebook fantasy numbers).
  • Data-led decisions — we log, verify, and keep it tidy.
  • OEM+ approach — drivability and longevity matter.
  • Support with common MQB headaches (boost control, misfires, fuel).

*Power figures depend on car condition, fuel quality, dyno type, and hardware.
