Why this is shown as a range

Because every car is different and our tuning is truly custom to the vehicle, output power after any form of tuning does vary between vehicles. Anyone saying it will be a fixed X hp after a tune is clearly applying an off-the-shelf map.

Stage options

Choose the right tuning package

Each stage is matched to the selected engine, its health, and the hardware fitted. The aim is useful, reliable performance rather than an off-the-shelf number.

Stage 1

Healthy standard car remap

The sensible first step for a standard vehicle in good condition. Built for stronger response, better drivability, and safe everyday performance.

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.
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.
