Product Details

Unlike "generic" diesel tuning systems, this advanced, self fit chip will be programmed specifically to optimise your Mercedes CLS-Class CLS320 CDI. And because it works in conjunction with your on-board computer rather than altering it, all engine safety functions remain operational. What's more, the system can be easily unplugged, leaving no trace of fitment, returning your vehicle to factory standard at any time.

The CHIP Express™ system simply plugs in using connectors which are identical to those originally fitted by the manufacturer - there are no wires to cut, just follow the supplied photo-instructions for your specific engine and you'll have the job done in minutes. Once installed, you will immediately feel the transformation. You'll pull away with ease, climb hills effortlessly and enjoy extra reserves of power when you need them. Your whole driving experience will be enhanced thanks to the significant boosts in performance. You'll feel the improved acceleration, the cleaner, crisper throttle response and enjoy smoother gear changes – turbo lag and hesitation off the mark will be replaced by a faster, more linear and instantaneous delivery of performance; you'll also appreciate a reduction in engine noise. Improvements in torque will transform low end dynamics and allow you to keep RPM's down by holding taller gears while using less throttle for similar speeds, helping you save fuel. Remember while most tuning companies aim to provide maximum power our aim is to also refine drivability and in gear flexibility, providing a wider spread of usable performance where you need it most!

Better Economy

By making your engine significantly more fuel-efficient, the CHIP Express™ digital tuning system means you can achieve substantially better economy from your CLS320 CDI too. You'll drive on a smaller throttle opening for a given speed and change gear less, getting you further on a tank of diesel!

* Typical economy results between 8-16% yet can produce up to 20% depending on engine tolerances, driving style and conditions. CHIP Express™ diesel tuning chips may also increase the maximum speed of your vehicle by up to 5%; applies to non speed limited vehicles only.

Ever wondered why the manufacturer didn't program it this way as standard?

Vehicle manufacturers are forced to compromise when they set up the engine's ECU, to create vehicles which will operate in a wide variety of markets and conditions.

  • Many countries, for example, impose emission controls which are far more rigorous than those we have in the UK.
  • Other countries relate their vehicle taxation systems to power output rather than engine size.
  • Some, like the UK, impose higher taxation for different emission levels.
  • In many cases power is deliberately restricted for future use.
  • Finally the manufacturers themselves often produce several different performance variants of a given model.

To meet all these different needs, they re-program the vehicle's ECU to change the engine requirements. Now, thanks to CHIP Express™ class-leading, state of the art solutions, you can benefit from greater low-down torque for improved pulling power, higher output for better out-and-out performance, and better fuel economy!

Feedback From Our Customers

David from Cambridge with a Mercedes CLS320 CDI 224 said: I am on third chip from Chip Express. I had one on my Rover 75 2.0 CDTi 131, then my Mazda 6 2.2D 163 and now on my Mercedes CLS320 CDI 224. I tried chips from other companies but they were all been sent back. This is the only chip I have had were you can feel the difference in the way the car performs. My Rover 75 was so much faster it was like a different car, I covered about 80.000 miles on that one. I then moved over to the Mazda 6 and would says this was a quarter as quick again and my fuel was so much better, I covered 60.000 miles with no problems. I recently upgraded my chip for use on my Mercedes CLS. The V6 engine is much smoother and more responsive. I have been using your chips for a few years now, covering thousands of miles each month as a chauffeur, your chips make driving so much better. Keep up the good work!
John from Boldon with a Mercedes CLS320 CDI 224 said: I have had the CHIP Express tuning chip fitted to my Merc CLS 320 CDI since 2009 and find it very good, power is increased for when needed and I achieve around 12% better fuel economy, spot on!
