Diesel Remap / Diesel Tuning


Here at Gloucester Landrover we specialise in diesel performance chips, diesel remapping via OBD port and general turbo diesel tuning and we pride ourselves in doing so without spoiling any of the principle reasons for buying a turbo diesel powered vehicle in the first place. We believe that key points such as their fabulous low down tractability, their reliability and of course the all-important fuel economy should never ever be compromised.

Our aim when creating diesel remapping is to gain the perfect increased power curve and fuel economy improvements yet retain all the safety parameters originally programmed into the engine management by the manufacturer so as to protect your engine and drive train from damage.

Gloucester Landrover Diesel Remap Will Give You The Following Gains

  • Increased horsepower
  • Increased torque
  • Better throttle response
  • Smoother power delivery
  • Improved fuel economy


Our power gains and improved fuel economy are achieved by very careful matching of parameters such as boost pressure, fuel delivery rates & pump timing along with adjustments to maps that electronically limit torque, throttle response and top speed. All this information in your ECU calibration file is carefully optimised to our exacting standards and then programmed back into your ECU and the vehicle comprehensively tested before we allow you to take the vehicle away.

When You take Your vehicle Away, You Will leave With

A Lifetime Warranty on the software

A no-quibble 30-Day Money Back Guarantee

Combined with an enthusiastic and skilled team, we are one of the leading Remapping and Chiptuning businesses specialising the Landrover range but can remap any diesel or make of car here in Gloucester.

When selecting a tuning company to modify your pride and joy, you have to ask yourself are you prepared to accept second best, from a second rate company flashing a potentially dangerous, cheap and nasty generic tuning file onto your vehicle? No of course not.


All modern cars and vans on the road today have an ECU (ENGINE CONTROL UNIT). This Engine Control Unit can almost be described as the vehicles ‘brain’ and contains a processor that takes information from various sensors throughout the engine. It analyses information such as the engine temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases as well as many more parameters. Using the information from these sensors it can then add the right quantity of fuel, at just the right time to provide a good mix of fuel economy, performance and emission control when pulling away, overtaking, pottering down the road or zooming down the motorway.


When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions manual, automatic and the weight difference of deferent models and trim using the same engine.

ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.


ECU remapping will not only improve the engines power and torque figures, it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible. Frequently, the vehicles power output is restricted by the manufacturer for no other reason than to ensure that the vehicle fits into a class to suit fleet buyers. As a driving enthusiast, you do not need or want such restrictions placed upon your vehicles ECU and its performance therefore you can benefit from the hidden power and torque locked away within your engine management system.

The other main benefit of remapping will be a reduction in fuel consumption. With the extra torque especially at the bottom of the rev range you will see a fuel saving, as it will require less throttle input to maintain motorway speeds, you can drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing or on gradients and even in start stop traffic

EPT - Eco Performance Tuning


The process is actually as simple as 1, 2, 3...

Our mobile technician comes to your location at a convenient time to download a copy of the unique existing file on your car's Engine Control Unit (ECU).

The unique file is then immediately uploaded to the Black Code Head Office where a personalised upgrade is developed for your individual vehicle.

The re-mapped file is sent back to the Technician and uploaded onto your vehicles ECU within the hour.

Why choose to have the manufacturer restrict your driving experience and pay more for fuel with less power? Instead you can trust Europe's leading economy tuning company to provide a tailor made upgrade and bespoke service that delivers. So, if you want to unlock the true potential of your vehicle, call us at Gloucester Eco Performance Tuning.

It is the modern day equivalent of tuning your engine with no visible modifications made to the vehicle.

Due to manufacturing shortcuts your car has been confined to run at less than its optimum efficiency and power.

Feel the incredible satisfaction of knowing you have lowered your emissions, reduced your carbon footprint and helped to save the environment while saving up to 15% of the money you spend on fuel.

Use EPT and you will immediately see a significant improvement in both the feel and drive-ability of your car. Your engine will feel more flexible, with a sharper throttle response and smoother, more progressive, power delivery. Put your scepticism to the test with our 100% money back guarantee if you do not notice a difference!
