Evolution Chips - The ECU Remapping Specialists

Citroen Turbo diesel tuning. Our Citroen diesel remapping will dramatically improve your vehicles performance & economy

Citroen Turbo diesel tuning

Here at Evolution Chips we specialise in Citroen turbo diesel performance upgrades. We pride ourselves in doing so without spoiling any of the principle reasons for buying a Citroen turbo diesel powered vehicle in the first place and 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 Citroen diesel performance chips, Citroen diesel remapping via OBD port or general Citroen turbo diesel tuning 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 Citroen so as to protect your engine and drive train from damage.

All our Citroen turbo diesel remaps are programmed to give a strong, linear power delivery right across the rev range.

Rest assured that we dont just look for a torque and power peak to make the numbers on your Citroen look good. We aim for maximum safe improvements everywhere so the vehicle feels like it has a bigger engine. Take a look at this video for an example of how the gains should be nice and linear across the rev range.

How is this achieved?

Our Citroen remapping power gains and improved Citroen 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 Citroen ECU and the vehicle comprehensively tested before we allow you to take the vehicle away.

We can also offer other services as part of your Citroen remap.

For example a vehicle used for motorsport may require removal of the EGR circuit, the DPF system and also benefit from having the vehicle speed limiter removed. Click the icons below for more details on those services.
