What this means for your Corsa
Turbocharged petrol engines respond well to calibration changes: boost and timing are the main levers, and the result is a flatter, stronger torque curve as well as a higher peak.
The ECU recorded for this variant is a Delco E78. Newer ECUs often protect their software, so we read the exact unit and version on the car before confirming the figures on this page.
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.
