Frequently Asked Questions

Is ECU tuning safe for my engine?
Yes. We do everything possible to mitigate risks—adequate safety margins, thorough testing, OEM methodology, and the best equipment available. This includes oscilloscopes with CAN bus analysis, advanced knock monitoring, precision gas analysis, and premium tuning tools. Our team is fully qualified, with MSc-level expertise in Automotive Calibration & Control.

How much power can I expect to gain?
Our remapping typically delivers up to 20% more power and torque on turbocharged petrol and diesel vehicles. Naturally aspirated engines usually gain around 10%.

How long does the tuning process take?
Most jobs are completed in a single day—typically a 10am drop-off and 2–3pm pickup.

Can I revert to factory settings later?
Yes. Unless the car has been previously tuned elsewhere, we can always restore the factory calibration. Even in most previously tuned cases, reversion is still possible—though not always guaranteed.

Will the tune be detectable by a dealer?
Technically yes, but in practice, even where dealers claim they can detect all tuning, they often cannot due to limitations in their tools. Detection varies by brand and model, so ask us about specifics for your car.

Does remapping affect fuel economy?
Yes. In most cases, you can expect 8–10% better fuel economy thanks to more efficient combustion and torque optimisation.

What happens if I modify the car after tuning?
Exhaust upgrades are well tolerated—our calibrations can even allow for decats if requested (note: this may affect WOF compliance). Intake modifications require more care: on vehicles with MAF sensors, poorly executed intakes can cause issues. These should not be attempted DIY without proper expertise and measurement equipment.
