Why this is shown as a range

Engine condition, fitted hardware, fuel and test conditions affect the measured output. The catalogue range is a guide; the target and testing for your vehicle are agreed before work starts.

Custom tuning vs off-the-shelf maps
ECU unlocking & dyno testing After 2020, some ECUs require unlocking, and some vehicles cannot be run on a rolling road without risking damage to the car.
A quick unlock is free; a more difficult unlock is billable. We can only confirm which is needed when we see the ECU. Where a car cannot go on the dyno, it will be checked on the road using a Magic Motorsport Road Dyno. See the dyno page for more details. Watch road dyno video
Reading the figures

Power, torque and the finished calibration

The ranges above are catalogue estimates. The torque curve, engine condition, fuel and fitted hardware affect the result for your vehicle. Tell us how you use the car so we can agree a target and testing plan.

Stage options

Choose the right tuning package

Each stage is matched to the selected engine, its health, and the hardware fitted. We agree the target and testing before work starts.

Stage 1

Specialist ECU/chip calibration

These vehicles use specialist EPROM, chip, bench, mechanical-injection or MBE work. We assess the ECU, engine condition and fitted hardware before confirming the calibration route.

Specialist ECU/chip calibration Price on assessment Contact us for an assessment
Power gain +77 to +86hp
Torque gain +108 to +120Nm
  • ECU and fuelling-system identification before work starts.
  • EPROM, chip, bench, rolling-road or mechanical setup selected to suit the vehicle.
  • Power-gain expectations retained where the engine and management have supporting evidence.
  • Final scope and price confirmed after assessing condition and fitted hardware.
Stage 2

Hardware-supported custom calibration

For cars with supporting modifications such as intercooler, intake, fuelling, or sensor upgrades. We tune around the actual hardware fitted.

  • Best when hardware changes need calibrating properly.
  • Bring a clear list of fitted parts before we quote or book.
  • Health checks are recommended if the car was bought already modified.
  • Can include Stage 1 features plus hardware-specific tuning.

Additional tuning options We have a number of additional tuning options available alongside Stage 1, Stage 1+ and Stage 2. Suitability depends on the vehicle, hardware, and intended use.
  • Sensor, limiter and driveability changes where supported
  • Emissions or motorsport-only software work where suitable
  • Hardware calibration for intake, exhaust, cooling and fuelling upgrades
Stage 3 and above

Custom tuning for serious hardware

We offer tuning for most performance modifications, from larger turbos and hybrid turbos through to cams, injectors, fuelling upgrades, ECU changes, sensors, and built engines.

Session type Custom Quoted after reviewing the vehicle and parts list
  • Larger turbos, hybrid turbos, supercharger changes, and boost control upgrades.
  • Camshafts, injectors, fuel pumps, MAP sensors, intake, exhaust, and charge-cooling changes.
  • Standalone ECUs, ECU swaps, built engines, and unusual conversion work.
  • Best handled with a clear parts list, intended use, fuel type, and current vehicle condition.
More information about Stage 3+
Included with tuning work Installation, checks, support, and calibration matched to the selected vehicle. Any mechanical issue found is reported clearly before extra work is carried out.
Before major hardware tuning We need to understand the parts fitted, the condition of the car, the ECU or management system, fuel type, and how the vehicle will be used.
