We specialise in diesel tuning and performance on Land Rover vehicles (and light commercial vehicles), and our team can service and repair most other makes of vehicles as well.

We use the latest technology to diagnose and repair ECU faults and provide an alternative choice to Main Dealer fault finding.

Over the past 8 years we have perfected tuning on TD5 Defender and Discovery but also on TDV6 and TDV8 in Range Rover, Range Rover Sport and Discovery 3 applications.

We were the first tuning company to enhance the performance and drivability (including removal of the speed limiter) of the new Land Rover Defender 2.4TDCI which has been fitted with the Ford Puma Diesel engine.

The development of this consisted in using two cars, one of which was the well known Allisport Land Rover Defender Puma, to commence the long and ongoing mapping process and saw us develop an exhaust downpipe as a replacement for the Catalytic converter.

We are the only tuner in the UK which has a dedicated diesel remap tuning centre specialising in Land Rover 4×4 performance tuning.

B.A.S also has a history of Special Build Projects (one of which is currently being documented monthly in Land Rover World magazine!) and we are currently working on a special TD5 VNT turbo conversion in conjunction with Turbo Technics.

We have also developed the B.A.S Live Switching re-map for the TD5 and we specialise in engine enhancements from Performance Chips to Re-maps.

From a standard road car to the serious off-road racer (such as the Paris Dakar race cars and Bowler Wildcat vehicles) our team can cater to all your road, rally or race needs.

There are a vast range of dealers and business customers in Europe and across the world using BAS for their tuning and development needs. In fact, many of our dealers re-sell our products in their workshops worldwide.

Over the years we have invested heavily in Land Rover Ford Mazda and Jaguar diagnostic systems (to name just some) keeping us on the cutting edge so we have everything on hand for all your diagnostic needs.
