Services - Frequently Asked Questions

Our ECU remapping service includes a comprehensive health check and diagnostic scan, reading and backing up your original ECU file, creating a custom bespoke map for your specific vehicle, uploading and testing the new map, and providing a road test to ensure optimal performance. We also provide lifetime software warranty and keep your original file backed up.

Stage 1 is performed on a stock (unmodified) vehicle and typically yields impressive BHP and torque increases within safe limits. Stage 2 is for vehicles with performance upgrades like exhausts, intakes, or intercoolers, and we recalibrate the ECU to extract full benefits. Stage 3 involves extensive modifications like turbo upgrades and requires custom motorsport-grade mapping for maximum potential.

Economy tuning optimizes fuel injection timing, torque delivery, and turbo boost for smoother power at lower revs, meaning your engine maintains speed with less throttle input. Many customers report 10-15% fuel efficiency gains, which translates to significant savings at the pump. This is especially effective on diesel vehicles but works well on petrol engines too.

Gearbox tuning is ideal for vehicles with automatic and semi-automatic transmissions, including DSG, ZF, and Tiptronic-equipped vehicles. We can sharpen shift speeds, optimize shift points, increase torque limits, and even enable features like launch control. We highly recommend pairing gearbox tuning with engine remapping for optimal results.

DPF/EGR/AdBlue deletions are intended for off-road or motorsport use only. For road use, we offer alternatives such as DPF cleaning services and can advise on the legal considerations. We always ensure customers are fully informed about the legal implications and alternatives available.

ECU remapping typically takes 1-2 hours, including diagnostics, mapping, and testing. Gearbox tuning takes an additional 30-60 minutes. DPF/EGR solutions vary depending on the specific issue but usually take 1-3 hours. We offer both mobile service and workshop visits to suit your schedule.
