What we actually do
A quick rundown before you book, so you know exactly what you're getting.
Performance Tuning
Performance remapping adjusts your vehicle's fuel, ignition, and boost maps to unlock power and torque your engine has but the factory setup doesn't use. It's done through the ECU rather than physical parts, so it's a same-day job with results you can feel straight away — sharper throttle response, stronger pull through the rev range, and a more engaging drive.
Economy Tuning
Economy remapping takes the opposite approach — instead of chasing power, we smooth out the power delivery and refine the fuelling to reduce how hard the engine has to work for everyday driving. It's popular with high-mileage drivers and van owners who want better miles-per-gallon without changing how the vehicle feels to drive day to day.
AdBlue, EGR & DPF Solutions
AdBlue (SCR), EGR, and DPF systems are all designed to cut emissions, but they're also common causes of warning lights, limp mode, and expensive dealer bills — especially on older or high-mileage cars and vans, where clogged filters, failed sensors, or a faulty AdBlue system can leave a vehicle undriveable. We diagnose the fault and, where appropriate, apply a software solution to get you back on the road.
Sensor Deletes & Fault Fixes
A single faulty sensor can trigger fault codes, warning lights, or limp mode even when the rest of the vehicle is fine. Where a sensor has failed or a part is no longer fitted, we can recalibrate the ECU so it stops flagging a fault that no longer applies — a straightforward fix for a problem that would otherwise mean a trip to the dealer.
AdBlue, EGR, DPF, and sensor delete solutions are carried out based on your vehicle's condition and intended use. We'll always talk through what's right for your car or van before any work is booked in.
Locked ECU?
Do you have a locked ECU on a post-2020 car/van? No problem here, we can unlock them and have it back with you within 5-7 working days. Please contact us for more info.
