Mustafa from Gabala, Azerbaijan with a Jaguar X-Type 2.0D 130 said:I was sceptical about the achievement of your product.... HOWEVER after use I am very happy! A quick 30 minute test drive and my Jaguar runs better then ever, even at an altitude of 2,569ft. I can now fully endorse your chips!
Ben from Bournemouth with a Jaguar XF MK2 20d 180 said:Once the chip was installed I took the car for a run. No problems with starting or tick over. No warning lights. Traffic has not allowed me to explore the performance but I'm looking forward to a run. FOLLOW UP: Running the chip has resulted in a significant increase in power, the car positively flies! This gives the much improved performance I was looking for. I would like to thank you for your excellent support and outstanding service. I can unreservedly recommend CHIP Express.
Michael from Tullnerbach, Austria with a Jaguar XF MK1 3.0D Edition 211 said:I received the tuning box this Monday (excellent service). After installation everything worked perfectly as expected. The new found power is just great. Everybody should try it! Thanks again!
Graeme from Galsgow with a Jaguar X-Type 2.2D 155 said:I fitted the Chip Express unit a few weeks ago, and have just had the car on an 800 mile round trip, Glasgow-Cardiff. Genuine 50mpg! Ran beautifully, with noticeably better acceleration, overtaking at 70 in 6th gear effortless, due to immense torque. I'm delighted. Thanks for a great product.
David from Manukau, New Zealand with a Jaguar XF MK1 2.7D 207 said:Fitted the chip in minutes and noticed the improvement in performance immediately, much smoother changes and a better power band. Have just check my fuel usage and now am getting an average on highway of 6.7L/Km, has been as low as 6.2L, the best I got before was 7.8L. Thanks, great product and delivery.
Len from Riverstone, Australia with a Jaguar XF MK1 3.0D 240 said:The chip certainly improves performance! When Jaguar made this model there was the 240PS 500Nm XF version and the 275PS 600Nm XFS, this chip has moved me up to this level. I was a bit reluctant to buy from overseas initially, but it has proved no problem at all. I would recommend this chip and your great service to anybody.
Alan from Cambridge with a Jaguar XJ 2.7D 207 said:Why by one? Why this company? I have a reasonably fast car anyway, what can it do for me? Well after hours of research of almost every supplier in the country and still in doubt I thought I would give it a go. It arrived just 16 hours after I placed the order! Now the real test, what does it do? 600 miles later and a lot of playing with the throttle I can confirm it DOES what it says in every way, loads more initial low RPM power… almost a second off the 0-60 and in kick down you almost have to learn to drive again, especially in the wet! My jaguar XJ now really drives like you expect a Jaguar to drive! Fuel consumption is better too (by about 6/7 mpg) but I am still having fun with the throttle so no real tests. Now that’s why you chip, and that’s why I recommend CHIP Express... brilliant!
Robert from Trefriw with a Jaguar X-Type 2.2D 155 said:Box fitted 2 weeks ago. Different car altogether. Will run at much lower revs and still pull away. Have just travelled from north Wales to Portsmouth and back and got 52 MPG at an average speed of 70 MPH. Excellent.
David from Yeovil with a Jaguar X-Type 2.2D 155 said:I have one of your units fitted, the performance gain is terrific, more than enough for my needs! On a long journey the economy has improved from 43 to 50 mpg. I will be happy to recommend your product to others. My car is now ALL that I want and will not be replaced as previously mooted. So much power and from an oil-burner at that!
“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.”

“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!”

“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!”

“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!”

“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!”

“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.”
