Before we can carry out a Stage 1 or Stage 1+ tune, your vehicle must meet certain requirements to ensure a smooth and successful tuning session.
Basic Requirements:
- The car must not have a check engine (MIL) light on, unless the issue is minor and will not interfere with tuning.
- If there is an existing fault, it must not affect key tuning parameters such as boost control, fueling, or ignition.
- We will carry out a basic check-over before tuning to identify any potential issues.
Exceptions:
In some cases, the vehicle may be booked for tuning specifically due to a fault, such as:
- DPF removal or recalibration.
- EGR disable or optimization.
- AdBlue system recalibration or removal.
However, we cannot tune a car if there are serious underlying faults such as:
- Turbo underboost or overboost errors.
- Fuel pressure faults affecting injection timing.
- Severe misfires or ignition system issues.
- Major sensor failures (e.g., MAF, MAP, lambda, or knock sensor faults).
If your car has a fault that prevents tuning, we will inform you and provide guidance on the necessary repairs before proceeding.
