Feedback From Our Jeep Customers

Peter from Perth, Australia with a Jeep Commander 3.0 CRD 218 said: Please let me tell you how fantastic your Chip Express unit is, out of the box it provided a noticeable improvement in performance and a minimum 10% fuel consumption saving on my Jeep Commander 3.0CRD. The engine has now done 10,000km!
Scott from Kansas, USA with a Jeep Grand Cherokee MK4 3.0 CRD EcoDiesel 243 said: I just wanted to check in and let you know everything is running smoothly as you promised. I can feel the extra toque and horsepower, lag from a standstill has been cured. I also did a foot to the floor acceleration and that threw no error codes on the supplied settings no matter how hard I tried. I'm very happy with the product and the customer service you offer, thanks again for all your help.
Tony from Toowoon Bay, Australia with a Jeep Grand Cherokee MK4 3.0 CRD 240 said: I am very happy with the tuner on my WK11 Grand Cherokee CRD 3.0L. I was a bit sceptical at first but after towing my 2.6 ton caravan from Sydney to central QLD I am convinced. The ease with towing is so much easier on the car than standard, I don't have to put my foot down as much going up hill AND get better mileage. Thanks for the great service, help and advice!
Nigel from Horncastle with a Jeep Grand Cherokee MK4 3.0 CRD EcoDiesel 250 said: I have fitted the Chip Express to my 2017 Jeep Grand Cherokee 3.0L V6 EcoDiesel and it is more than meeting my expectations. Smooth delivery and an impressive increase in noticeable power, installed unchanged from factory settings.
Brian from Chelmsford with a Jeep Cherokee MK3 2.8 CRD 163 said: Thank you for an excellent service. I fully endorse the views of other customers regarding the claims of this product. One may or may not find a rival product as good as CHIP Express. One certainly will not find a company that delivers better customer service. In my opinion, the measure of a good company is how well they deal with any unforeseen problems. They were as good as their word, I can not recommend CHIP Express highly enough.

What others are saying...

“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.”

“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!”

“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!”

“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.”

“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!”

“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!!!”
