Release up to 40% more POWER
and 20% better ECONOMY !
Fit yourself in minutes –
feel the difference or your money back!
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.
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.
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.
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.
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.

“A good product and a good service deserves recognition: I fitted a CHIP Express unit to my Insignia. What an amazing bit of kit! My fuel economy and performance went way up and with the mileage I do was a Godsend! On a run to Aberdeen from Hull I returned an average of 62 MPG and I drive quite energetically! I've just taken up the trade in offer and saved a few quid on a new system. The Vauxhall has now gone with 125,000 trouble free miles and I have changed car to a Volvo S60 D3. I'm looking forward to fitting the Chip Express unit and reaping the rewards, thanks guys!”

“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.”

“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!!!”

“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!”

“Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! 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.”
