Engine Remapping


We have worked extremely hard and invested heavily to offer our customers bespoke custom written maps for their vehicles. Our specialist area is German vehicles VW, Audi, Seat, Skoda, BMW, and Mercedes (we do cater for other manufacturers)
Many hours have been spent on the dyno testing our remaps to ensure our software is not compromising the safety limits of a vehicle whilst still providing high quality tuning and improved performance.
We have invested in only genuine and relevant tuning tools to use when programming your vehicles ECU. Your vehicles health is our main priority whilst it is in our care. We specialise in German Autocare at our service centre and many of our customers use us for more than just tuning due to our specialist mechanical and diagnostic knowledge.
All vehicles will be provided with a health check report prior to any remapping as we do not like to disappoint our customers and therefore will not work on a vehicle with faults present at the time of tuning.
As we can offer non-generic custom remapping software, we provide several different options available to suit your vehicles modified parts setup.

Rolling Road Dyno (2WD) available at additional cost
Stage 1 - 2 - 3
Available Addons
Decat Software
(Over-run Maps) - Burbles - Crackles - Pops and Bangs

As motor enthusiasts ourselves our business model is set to provide fellow motor enthusiasts a one stop shop for servicing, supply & fit of performance parts and tuning to match your vehicles modifications.
We provide an honest tuning service and aim to keep our remapping customers for general servicing and diagnostics work that they may require in the future. We will still be around next week/month/year if you need to speak to us about anything relating to your vehicle unlike some of other map flashers offering cheap generic or dangerous software.
We work with some of the biggest names in the performance parts industry offering our customers the best products at great rates. Head over to our online shop and see what we have for your vehicle.

For any more information feel free to give us a call and we will be happy to assist with any enquiries you may have.
