Cardiff, Bridgend, Vale of Glamorgan & surrounding districts
Mobile ECU remapping, tuned on your driveway.
Stage 1 from £249, Stage 2 and Stage 3 from £325, across Cardiff, Bridgend, Swansea and Newport. Your original file is always saved, so the car can be put back exactly as it was.
More usable power
Stage 1 maps sharpen throttle response and lift mid-range torque where you actually drive.
Economy options
Economy maps chase MPG instead of power — ideal for motorway and van mileage.
Safe, tested maps
Written for your exact engine and gearbox, with the original file always saved.
Fully mobile
Done on your driveway or at work — nothing to drop off, nothing to collect.

Optional calibration features
Availability varies by vehicle, ECU and intended use. Compatibility and pricing are confirmed after vehicle identification; selecting a feature during booking is a request, not confirmation that it is suitable.
Customers are responsible for ensuring modifications comply with applicable road-use, emissions and MOT requirements. Certain calibration options may only be appropriate for vehicles not used on public roads.
Prices cover the map, the road test and the saved original file. Performance figures shown are estimated gains for a healthy vehicle. Actual results can vary depending on vehicle condition, specification, fuel quality and modifications.
How it works
Four steps, one visit
Check your figures
Put your registration or your make, model and engine into the power checker to see the estimated gains.

We come to you
We carry out diagnostic checks, safely read and save the original ECU software, then program the vehicle using the appropriate OBD, bench or boot method for the ECU fitted.

Road use and compatibility
Vehicle-specific advice before programming
