Feedback From Our Jaguar Customers

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.
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!
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.
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.
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!
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!
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.
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.

What others are saying...

“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!!!”

“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.”

“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!”

Frazer from Skirlaugh

“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!”

Kia Sportage MK3 1.7 CRDI 116

“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.”

“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!”
