Feedback From Our Jaguar Customers

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!
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!
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.
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!
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!
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.
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.

“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

“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!!!”

Audi A6 MK4 3.0 BiTDI 313

“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.”

Land Rover Discovery (3) 2.7 TDV6 190

“Many thanks for your fantastic service! Unit ordered Sunday, delivered Tuesday am!! Unit now fitted and, as promised, the car is transformed. Winding country lanes tackled quite happily in fifth gear. Cruising on much smaller throttle openings and immediate response on acceleration. The car behaves as a mini car should behave. I had some initial doubts about spending quite a large amount of money on this item but it is worth every penny and would not hesitate to advise anyone to do similar.”

“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!”

Land Rover Freelander (2) SD4 190

“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!”
