Overview
Petrol Engine Remapping in Midwales
Petrol engines are controlled by maps for air-fuel ratio, ignition advance and, on turbocharged cars, boost pressure. Factory settings are cautious to cope with poor fuel, hot climates and neglected servicing. A remap tunes those maps for your engine within safe limits, which shows up as sharper throttle response and stronger acceleration.
Turbocharged petrol engines respond best, because boost can be re-calibrated. Across the 980 petrol engines in our catalogue, a stage 1 remap adds an average of 27 bhp and 51 Nm.
Who it suits
- Turbocharged hatchbacks, saloons and estates
- Drivers who want stronger, easier acceleration
- Cars that are well maintained and regularly serviced

What to expect
- A more responsive throttle and stronger mid-range pull
- A bigger percentage gain on turbocharged engines than on naturally aspirated ones
- Figures that vary with the car's condition, so we quote them as indicative
Worth knowing
- Naturally aspirated petrol engines usually gain less, because there is no boost to re-calibrate.
- Tell your insurer about the remap before you book.

Questions
Petrol Engine Remapping: your questions
Will a petrol remap work on a non-turbo engine?
It can improve response and give a modest gain, but the improvement is smaller than on a turbocharged engine.
Do I need better fuel?
Good quality fuel is recommended for any performance-tuned petrol engine.
Can I go back to standard?
Yes. The original software is saved before any change, so it can be restored.
