Diesel Tuning with CHIP Express™

More Power

Plug-in the CHIP Express™ diesel tuning chip and feel the extra power – instantly! Up to 40% more power means a sharper throttle response. Say goodbye to flat spots and turbo lag – say hello to smoother gear changes and boosted power. Enjoy a livelier feel, as if you'd chosen the bigger engine option.

More Torque

Fit the CHIP Express™ digital diesel tuning box for more torque too. You'll immediately notice better acceleration from low down in the rev range and when using taller gears. And that means more pulling power - precisely what you need if you tow a caravan, a horse box, a boat or if you drive a heavily laden vehicle like a van or pickup.

Better Economy

With ever-rising fuel costs you'll appreciate up to 20% better economy. Greater power and torque means you'll pull away with ease, change up through the gears much sooner and change down less. Auto boxes will respond in the same way too. This keeps your RPMs lower and is significantly more fuel efficient.

What is a Chip?

A programmed electronic microprocessor controlled device that simply plugs inline within the engine bay of the vehicle; it remains permanently fitted when in use but can just as easily be removed without trace.

When fitted it continually monitors and works to boost your engine's efficiency, all within governed safety parameters.

Remember the CHIP Express™ digital diesel tuning system is not a "replacement chip" where your ECU is physically opened and its original chip replaced (thus immediately invalidating your vehicle warranty). Nor is it a "remap" whose settings can be detected and even deleted during routine servicing. The CHIP Express™ plug-in digital tuning system is an additional sophisticated microprocessor controlled tuning chip which will give you substantial, immediate performance and fuel consumption gains.

So, whether you drive a manual or an automatic, a car, van, motorhome, tractor or even a boat, we have a diesel tuning chip for you - there are no wires to cut and no special tools needed, it takes just minutes to fit.

Works Out of the Box!

The system arrives presentation packed and complete with everything you need to fit it yourself in minutes.

This includes digital tuning chip itself with the correct cable for your vehicle along with a weather-resistant mounting pouch and Velcro fixings, all designed for quick release and re-fitment if necessary.

You then simply plug it in following the detailed, engine-specific photographic instructions provided.

The system is designed to give optimum results right out of the box without needing additional complicated setting and tweaking.

“Received the kit for my Honda CR-V this morning - less than 24 hours after I ordered it. Simple, clear instructions. I spent 5 minutes reading through the instructions and it took me just under 10 minutes from start to finish to install the system - and I have no mechanical knowledge or experience, so if I can do it anyone can. Left the setting on the pre-configured mark and went for a test drive and WOW! Immediate and noticeable increase in power and especially torque. Could not resist tweaking it so increased to the next level and went for another test drive. DOUBLE WOW! I am amazed! I think I shall leave it on this setting - it definitely does not need any more! All in all I can recommend this system - it does exactly what it says it will do and it is a simple 10 minute job to install.”

“I have a 2015 Mercedes E250 CDI Cabriolet and recently fitted the chip. It took minutes to fit the chip itself and a further few mins of fettling to find the best place to stow the item, all in all a very easy solution. I bought the chip for the extra performance, more torque than power, as opposed to economy gains, and it has delivered it in spades. I took my car out for spin prior to fitting then again on the same road post fitting and I could feel the difference instantly and everywhere. I highly recommend this product for the grin factor, the economy gains will come as a result of the chip which to me is just a bonus.”

“Superb Skoda - Superb economy! Just to say that I fitted the CHIP Express last weekend and I am now getting 50 MPG on and around town (compared to 44 MPG previously) and a phenomenal 59 MPG on this mornings commute to work (120 mile round trip). Previous average was 46 MPG. I was initially very sceptical about improvement but sensible use of throttle and with unit in default setting I have been blown away by the improvement! I am recommending to friends, work colleagues and family!”

“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!”

“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.”

Citroen C6 2.7 HDi 204

“I was a sceptic at first, then after reading the experiences others had been through I decided to give it a go. I bought a new 1.7 CRDI Sportage, not the 2ltr purely for better fuel figures. Whilst this engine pulls very well in standard form, and was returning 44-45mpg even during the first 500 miles I had to go down the CHIP Express route. Well, there is absolutely no point in forking out the extra 2 grand for the 2 litre model when you can get the 1.7 and spend much less to get 2 litre power figures. Excuse the cliché’s, but this car is transformed and by a big margin too. From what I can remember about my 2 litre test drive, my 1.7 now pulls better than the 2 litre version. The low-down grunt is remarkable and pulls like the proverbial train. Fitting took minutes and was effortless, the box was kept on factory settings, I feel there is no need to mess with it. Needless to say I am now a very happy boy and would without question take this route again. I would recommend this to any diesel Sportage owner. Many, many thanks for a remarkable product and a customer service that is rare in this country!”
