Feedback From Our Jeep Customers

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!
Patrick form Calgary, Canada with a Jeep Grand Cherokee MK4 3.0 CRD 250 said: Super easy to install. We have left it on the default setting for now and do notice a significant increase in power and all the lag has disappeared when you step on the gas. We do see some improvement on fuel economy but it has also been -30 outside here!
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.
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.
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!
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...

“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!”

“Just to let you know I have fitted the unit to my Peugeot 407 SW 1.6 down here in the Algarve, where it is warm and sunny, and, as with our Volvo D5 system, simple to fit, the instructions are excellent and it runs beautifully. I initially bought a cheaper unit from another company, but it did not actually work! This is my second Chip Express unit and again the results are remarkable, much better response, a significant increase in power and better economy, in my view an outstanding unit! Thanks again.”

“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!”

Vauxhall Insignia MK1 2.0 CDTI ecoFLEX 130

“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.”

“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.”
