Mobile tuning

Our sister company Remaps UK comes to you

We do not run a mobile service from the Maidstone workshop. Everything we do is done on the ramp or on our own rolling road, because that is where we can measure what the change actually did. A laptop on a driveway cannot tell you that.

If you cannot get the car to us, our sister company Remaps UK will come to you. They fit the same tuning files, written here and tested here, at your home or your workplace.

What Remaps UK do

They are a mobile-only business with their own engineers, their own prices and their own booking diary. An engineer comes to the car, reads the ECU, writes the file we hold for that exact engine, and checks the car over before and after. Stage 1 engine tuning, gearbox tuning, economy remaps, and the AdBlue, DPF and EGR work.

We supply the software. Anything to do with the appointment itself, ask them.

What still needs the workshop

  • Anything above Stage 1. Stage 2 and Stage 3 change what the engine is asked to do, and neither of us will publish a figure for it that has not been run on the rollers first.
  • Rolling road work. Before and after runs, mapping sessions, and a printed graph of what your car actually made.
  • Hardware. Intercoolers, downpipes, turbos, injectors, anything that has to be fitted rather than flashed.
  • Servicing, repairs and diagnostics on the ramp. A fault that needs the car in the air is not a driveway job.

Two businesses, one set of files

Where the files come from

Every file Remaps UK fit was written here, for that exact engine, and tested on our own 2,000bhp 4WD rolling road before it left the building. That is the part we do.

Where the work happens

Their engineer does the fitting at your door. Ours does it on the ramp, with the car strapped down and the fans on, which is the only way we can hand you a graph afterwards.

Who to ask

Booking, pricing and anything about the mobile appointment goes to Remaps UK. Rolling road time, Stage 2 and Stage 3, hardware and servicing stay with us. If you are not sure which one you need, send us the registration and we will tell you.

How it works

  1. Get a price. Send Remaps UK the registration and they will come back with what they can do for that engine.
  2. Book a slot. You pick the time and the address, home or work.
  3. Health check first. The engineer reads the fault memory before touching anything. If the car is not fit to tune they will say so, rather than sell you a remap you should not have.
  4. Tune and road test. The file goes on, the car goes out, and they check it drives as it should before they leave.
