Stage 1 for a standard car
A Stage 1 performance remap changes the calibration in the engine control unit, or ECU. On a suitable car with standard hardware, it can change how the engine delivers torque and responds to the accelerator. A driver who wants better response during everyday overtakes may be looking for a different result from someone who wants the car to pull harder at high revs. Tell us what you want to change about how the car drives.
Stage 2 for a specific hardware setup
Stage 2 means choosing a calibration for the hardware already fitted. An upgraded intercooler is one example of a change that can matter, but the requirements depend on the engine and file. Send the parts list with your enquiry. If you’re still deciding what to buy, check the tune requirements first.
What you pay for
A* lists Stage 1 Performance at £240 and Stage 2 ECU tuning at £280. Stage 2 is the ECU tune. We confirm the setup and any additional work before booking. If your aim is lower fuel consumption, compare Stage 1 Eco before choosing a performance tune.
Details that help us check the car
Send the registration, engine, any current remap, and a list of modifications. Mention warning lights or a change in how the car drives. If it’s under warranty, ask the warranty provider how it treats tuning before you book.
