- Daily drivers who want stronger mid-range pull and a sharper throttle.
- Anyone who wants the biggest gain we list without fitting hardware.
What this means for your Golf
On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.
The ECU recorded for this variant is a Bosch MED17.5.25. We read the ECU on your car and compare it with the software listed here before any work starts, so you know what to expect before you commit.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.
