    G8X M3/M4 tuning FAQs

    What's included in a G8X M3/M4 tuning package?
    Every package includes the ECU unlock, Tom Wrigley Performance software for your chosen stage and a gearbox (TCU) tune. You then add any hardware you want fitted, and choose where to drop your car off.
    What's the difference between Stage 1 and Stage 2 on the M3/M4?
    Stage 1 is software only and works on a standard car. Stage 2 needs upgraded downpipes and an OPF-delete midpipe. Upgraded air filters or an intake give extra gains on top.
    Where do I drop my car off?
    You can drop your car at R44 Performance HQ in Wembley, London. We fit your hardware, transport the car to Tom Wrigley Performance in Oswestry for tuning and bring it back to us for collection. Or you can take it straight to Tom Wrigley Performance in Oswestry, where your hardware is fitted and the car is tuned on site.
    Is fitting included in the price?
    Hardware fitting labour is quoted separately. Once you've ordered, we'll contact you to confirm the labour cost and book your drop-off date.
    I already have some parts fitted. Can I still order?
    Yes. Choose 'Already fitted to my car' on any hardware step and the configurator will match the right stage for your setup.
    Are midpipes and downpipes road legal in the UK?
    In the UK, midpipes are not road legal if they remove a secondary catalytic converter or petrol particulate filter (OPF) or breach noise regulations. You are responsible for ensuring your setup is legal for your intended use.
