Frequently asked questions

Stage 1 is an entry-level tune that improves power, torque, and throttle response without major modifications. Stage 2 involves additional bolt-on upgrades like exhausts or intakes for greater performance. Custom builds go beyond Stage 2, including full performance transformations tailored to your goals.

Yes — when done professionally, tuning is safe. At Forza Tuning, we carefully calibrate every tune for your car’s engine and components, ensuring reliability, drivability, and long-term performance.

Absolutely. Most modern cars can be returned to factory settings with a reflash or ECU reset, allowing you to enjoy tuning now and revert if needed.

It depends on your manufacturer’s terms. Many brands may limit warranty coverage if modifications are detected. We recommend checking your car’s warranty and we’re happy to discuss safe tuning options that minimise risk.

Power gains depend on your car and the stage of tune. Stage 1 typically delivers a 10–20% increase in power, while Stage 2 offers higher performance, with supporting modifications potentially boosting power by 30–50%.

For Stage 1, no additional upgrades are usually required. For Stage 2 and Custom Builds, bolt-ons such as exhausts, intakes, or intercoolers can maximise performance and reliability. We can advise exactly what’s needed for your car.

Most Stage 1 tunes take a few hours, while Stage 2 and Custom Builds can take longer depending on modifications. We’ll provide a clear timeframe when you book your appointment.

Absolutely. You’re welcome to provide your own parts, and we’ll install them professionally while ensuring they work seamlessly with your car and tune.

We recommend following your manufacturer’s service schedule, but some tuned cars benefit from more frequent oil changes and inspections of performance parts. We can advise a tailored service plan for your specific tune and modifications.

A poorly executed tune can cause engine knock, overheating, excessive wear, or even component failure. That’s why professional calibration and understanding of your car’s internals is critical — we prioritise safety and reliability with every tune.

Our tuner is a mechanical engineer with extensive experience in automotive performance. This ensures every tune and modification is backed by technical expertise, precision, and a deep understanding of your car’s mechanics.

ECU remapping optimises your car’s engine control software for more power, torque, and efficiency. We offer two approaches:

• Piggyback ECU: An additional module works alongside your stock ECU to adjust performance without altering factory settings.

• ECU Unlocking / Full Remap: The ECU is unlocked, allowing full customisation and precision tuning for maximum performance.

Yes — we can dyno your car to accurately measure power, torque, and performance. This ensures every tune is precisely calibrated and optimised.

Yes — our tunes are designed to maintain your car’s factory features and drivability, so you can enjoy enhanced performance without sacrificing comfort or safety.

Yes — we provide clear performance data so you can see exactly how much power and torque your car has gained from the tune.
