Product Details

Unlike "generic" diesel tuning systems, this advanced, self fit chip will be programmed specifically to optimise your BMW 5 Series E60 / E61 525d. 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 E60 / E61 525d 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!

Before
After
 
 

* 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

Tomi from Helsinki, Finland with a BMW 5 Series F10 / F11 520d 184 said: Hi! Fitted my tuning box in 10 minutes and went for a test drive. Have to say it was everything you promised! After first acceleration I couldn´t stop smiling! :) Much more responsive car now and the torque is great! I have already recommended your great product! Thanks a lot!
Alan from Whiston with a BMW 5 Series E60 525d 177 said: Just fitted chip set box to my Beemer, very pleased with the result. More power, faster acceleration, pulls a lot better too, just as promised, and all this on the standard setting. Just thought I would let you know and thank you. I will be recommending to others!
Peter from Keighley with a BMW 5 Series F10 530d 245 said: Thanks CHIP Express, you've done it again! I have been using your chips since 2008. First on an Audi A6 2.7 TDI, which increased my MPG from 37 to 40 together with a marked improvement in power delivery. When I changed cars to an Audi A8 3.0 TDI, you reprogrammed the old chip for very sensible money and once again improved power output and my MPG. I have been so satisfied with the service provided that, when I changed again to a BMW 530d, my first port of call was to yourselves and you have not let me down. From contacting you and you returning the new chip took 5 days, and within 5 minutes this was installed. I can report that over the last week I am starting to get an increased MPG. I cannot recommend your company too highly. First class product, first class service. A pleasure to deal with. Anyone thinking of improving their MPG and power output in these harsh economic times would be well advised to consider CHIP Express before many other alternatives.
Simon from Hamiltonsbawn with a BMW 5 Series F10 525d 204 said: I recently purchased a chip for my 2011 525d. Instructions for fitting were specific for my car. Now fitted you can really feel the difference. Everything is much snappier and power delivery is very linear. This is an excellent system. I have covered about 3000 miles with this chip and on my 48 mile run to work (a mix motorway and A roads) I get 47 mpg. This obviously drops when my right foot gets too heavy but it is nice to know I have the option to save fuel or save time. Would definitely recommend.
Dave from Hainaut, Canada with a BMW 5 Series F10 520d 184 said: Installed the tuning module last week and I am extremely pleased with the results. Prior to installation I enjoyed driving my car, but now I really love driving the car. Makes me wonder why anyone would spend 11000 more to purchase a 530D. During the past week I tried the various settings and have had positive results with all levels. Fuel economy has only improved approximately two percent at highest setting, probably because the increased power entices me to drive more quickly. Recommended for the F10 520D!
David from Sankt Gallen, Switzerland with a BMW 5 Series F10 M550d 381 said: Feedback to say that I am more than happy with the increased performance and economy from the tuning. Fuel costs are very important but so is arriving on time to a meeting. My son Mark first introduced me to the possibility with my BMW 525d xDrive. Since then we have used this system on the two BMW 320d xDrive's and the BMW 740d xDrive. I recently part-exchanged the BMW 740d for a BMW M550d triturbo. The benefits pay for the system in a short time and then it is a win-win situation: A win with more performance and a win with more economy! FOLLOW UP: I am very happy with the results. The high speed response is far better. Thank you very much for the upgrade!
Steven from Melvourne, Australia with a BMW 5 Series F10 520d 184 said: I have just installed mine in a 2012 BMW 520D with outstanding power improvements. Specifically it got rid of the turbo lag, which in my opinion I thought was dangerous. The CHIP Express kit has made the car better to drive and more importantly safer. BMW, you should take note of this system for future car releases!
David from Duns with a BMW 5 Series F10 535d GT 299 said: Useful improvement in economy of around 10% on shorter journeys, this becomes more like 17-20% on longer trips. I also used the system on a Seat Ibiza 2.0 TDI CR 143 which also resulted in much improved engine response and economy. This is an excellent product!
Tim from Morthoe with a BMW 5 Series F10 520d 184 said: On Saturday I received my upgraded chip - great customer service! Originally fitted to my BMW E60 530d performance and economy easily matched what was quoted and I was more than pleased. Having just fitted the reprogrammed chip to my new 520d I just wanted to inform you that once again performance is very impressive. Fitting was also very easy thanks to the clear instructions. I will continue to recommend you, a fantastic product from a fantastic company!
Nick from Penrith with a BMW F10 520d 190 said: I have the chip installed and racked up about 1,000 miles. The difference in torque and mid-range acceleration is palpable and very welcome in such a big car. I don’t monitor fuel consumption particularly closely however I certainly haven’t noticed any degradation in that respect despite my heavier right foot whilst enjoying the extra performance.
David from Westerham with a BMW 5 Series F10 / F11 520d 190 said: I have fitted the unit with no stress at all, I think I was over thinking it to be honest. Anyway, I cannot believe the difference in has made to my car. the is so much pull it is like a full engine transplant. Thank you very much.
Raj from West Drayton with a BMW 5 Series F10 535d 313 said: I have just sold my BMW 535d which was previously fitted with your chip box. After 2 years of fault free driving, I have nothing by praise for CHIP Express. I never got a single fault code, nor did I get any excessive smoke, just a noticeable power increase that made the car more enjoyable to drive!
Stuart from Newcastle with a BMW 5 Series E60 535d 286 said: I had this chip on the wife's Golf 2.0 TDI MK6. It made a massive improvement to performance and MPG, especially on long motorway drives, however considering she only did a 4 mile combined trip to work it was pointless, so I decided to have the chip reprogrammed for my BMW. On the 535d it has given me instant throttle response, normal drive mode is very smooth and responsive without flooring the pedal and sports mode is like being on a runway train. Absolutely delighted yet again, thank you.
Malcolm from Bournemouth with a BMW 5 Series E60 520d 177 said: Fitted unit over 3 years ago on BMW 5 series M sport Touring 20d. Consumption 48-56 mpg, mid range grunt and acceleration brilliant on a vehicle with 130,000 on the clock. Have to teach right foot I am no longer a teenager!
Hugh from Ashtead with a BMW 5 Series E60 520d 163 said: Am very pleased with the product bought for my BMW 520d. The claims you make are all borne out by the results I am getting. A really good car is even better as a result. Thank you also for your prompt service.

What others are saying...

“A friend recommended one of your "gadgets" a year ago and being not-very-techno (but Scottish and keen to save money!) I bought one. The gizmo has TRANSFORMED the performance of my Land Rover Freelander 2 TD4 AND improved the fuel economy by a genuine 15%; so much so that I have bought another one for our Freelander 2 SD4 which is now a REAL Q-car! (And of course saves fuel...) I have never written a review before (though strangely I do read them and take notice of them, whilst half-believing that they are written by the owner's chums!) so to have made me pick up pen & paper so to speak - I MUST be delighted! Thanks for making technology so simple and so successful!”

“As do many, I took the 'if it sounds too good to be true, it probably is' approach to performance chips. But CHIP Express were recommended by an impeccable source who had had experience with their product on my model of car - a Citroën C6 with the 2.7 HDi twin turbo diesel. Following a first rate response to a query, the product has delivered in spades. Ten days and more than 1000 miles of mixed town, country, low and high speed driving later I am certainly getting more than 10% more from a gallon, and probably 15%, and the performance is markedly better. Low speed response is immediate and has eradicated what I took to be baked-in lag in a big automatic turbo diesel, and mid-range acceleration is silky smooth, including up inclines. A very good car has been turned into the excellent car I had hoped for all along.”

“I must say l'm delighted with the improvement from your chip, its on the standard settings and the difference in the car is amazing!!! I have a smile on my face every time I get in the car, and there is about 5-7mpg improvement. With the mileage l do, l can see myself getting my money back in no time at all. So if your a doubter like me, don't be because its one of the best things l've ever bought!!!”

“Be assured, this is NO gimmick. Arrived yesterday (less then 24 hours after the order was placed) and fitted today. The fitting was easy especially with the photos and instructions sent with the chip. The first thing I noticed was the responsiveness of the engine from a standing start, no more lag. I then went on a 30 minute drive both motorway and sideroads and my average fuel consumption went UP from 33.3mpg to 38.7mpg. My motorway speed varied from 60 to 85mph and the sideroads from zero to 40mph. I am so pleased with the whole result. This is worth every single penny paid. Thank you!”

Ford Kuga MK2 2.0 TDCi 163

“May I congratulate you on this diesel tuning product as it has made a noticeable difference to my Land Rover Discovery. I have tried other diesel tuning boxes for my previous vehicles (Kia Sorento, Peugeot 206 and Vauxhall Vectra)... and they all produced slight engine stuttering under certain load conditions. The CHIP Express system does not show any evidence of this and is equal to the likes of an ECU remap (which I have also had done before) for smoothness and noticeable power gains. This would be the only diesel tuning product I would recommend.”

James from Callington

Land Rover Discovery (3) 2.7 TDV6 190

“Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.”
