Mobile ECU Remapping Specialists Covering Cranleigh
Custom-written maps, not generic files. We remap petrol and diesel engines for drivers across Cranleigh, sharpening throttle response, adding usable mid-range power and often improving real-world economy.
Custom ECU remapping for Cranleigh drivers
Cranleigh sits comfortably inside our core patch. We reach it via the B2128 and the A281 nearby, cover every GU6 address, and are frequently just up the road in Godalming — so waiting days for an appointment is rare.
Think of a remap as the service the factory never offered: the same engine, the same hardware, but with software matched to real roads instead of worst-case scenarios. Done professionally, it’s the best value-for-money upgrade a turbocharged car can have.
We tune for drivability first — smooth power delivery, no flat spots, no drama — then performance. Your original map is archived before installation and can be restored at any time, for example before a dealer visit or when you sell the car.
Appointments across Cranleigh are fully mobile whether you’re right in the centre or out towards Godalming, and most vehicles are completed within 1–2 hours at your home or workplace.
While we’re with you, we can often handle more than one job in a single visit — we also offer AdBlue delete, DPF removal and EGR delete in Cranleigh.

ECU Remapping in Cranleigh — your questions answered
Do you tune vans and 4x4s too?
Absolutely. Vans, pickups and 4x4s respond very well to a torque-focused map — easier loaded driving, better towing and often improved economy on a run. Tell us the vehicle and we’ll quote expected figures.
Do you cover all of Cranleigh?
Yes — we cover every part of Cranleigh and the surrounding villages, including all GU6 addresses. We’re fully mobile, so we come to your home or workplace at a time that suits.
How much power will my car gain?
It depends on the engine. Turbocharged diesels typically gain 25–35% more torque, turbocharged petrols 20–30%, and naturally-aspirated engines a more modest 5–10% with improved response. Call with your registration and we’ll quote expected figures for your exact model.
Can a remap really improve fuel economy?
Often, yes — particularly on turbo diesels. Extra mid-range torque means fewer downshifts and less throttle to maintain speed, and dedicated economy maps prioritise MPG over outright power. Your driving style remains the biggest factor.
Is remapping safe for my engine?
A professionally-written map stays inside the engine’s designed tolerances — the same hardware handles far higher outputs in other markets and models. We tune conservatively for reliability, and your original file is archived so the car can always go back to standard.
