About This Service
ECU remapping adjusts the software parameters of your engine control unit to unlock the performance that manufacturers deliberately restrict. At Boost Garage, we use professional remapping tools to safely increase power output, improve throttle response, and in many cases improve fuel economy — particularly on diesel vehicles. All remaps are custom-written for your vehicle.

Frequently Asked Questions
How much power gain can I expect?
Diesel vehicles typically gain 20–40% more power and torque. Petrol vehicles typically 10–20%. Gains depend on the specific engine.
Will it affect my insurance?
You must inform your insurer of any remap. Many specialist insurers cover modified vehicles at reasonable rates.
Is remapping safe for my engine?
When done professionally within safe parameters, yes. We never push beyond safe limits for your hardware.
Can it be reversed?
Yes — we always keep your original map and can restore it on request.
