Feedback From Our Vauxhall Astra Customers

Shaun from Thetford with a Vauxhall Astra MK5 H 1.9 CDTI 150 said: Astounded, simply astounded! A great car utterly transformed into a thoroughbred with blistering performance. I'm finding myself looking for excuses to use the car more and more, it really is that much more fun to drive. The fact that no tools are required for fitting was a real bonus and economy is now much better too, I'll certainly be recommending this plug-in chip to friends!
Martin from Peterborough with a Vauxhall Astra MK6 J 2.0 CDTI 165 said: I purchased a CHIP Express for my new 2012 Vauxhall Astra SRI 2.0 CDTi. Well what can I say? What an improvement from just adding the chip! It has improved all what it says on the box. I've just increased the power to max and I am still getting 48mpg. I would really recommend these chips to anyone who has a diesel. The power and torque is such an improvement over standard!
James from Gloucester with a Vauxhall Astra MK5 H 1.9 CDTI 150 said: I can't recommend this system highly enough! I have had a CHIP Express system fitted to my Saab 9-3 1.9 TID 150 for a few years and now I've bought another chip for my Astra Twin Top. The 9-3 and Astra share the same engine so I could of just swapped over the box from one car to the other - but because the CHIP Express has transformed the driving ability and economy of the Saab so much I would not want either car without it. Incidentally when I bought the Astra the previous owner gave me a tuning box that he had fitted. Unfortunately it was nowhere near as good as yours and when fitted after a few days it put the car into limp home mode causing a light to pop up on the dash. Anyway as expected and once again the CHIP Express box has worked wonders, effortless power, no flat spots and far better economy. It's changed the Astra convertible from not just being fun in the sun but fun all year round!
Craig from Milton Keynes with a Vauxhall Astra MK6 J 2.0 CDTI 165 said: Ordered Wednesday received Thursday, a great service. It was a doddle to fit on my Astra and its running very well with just that kick of speed on hand should you need it. I am finding myself going out in my car for drives, not because I have to but because I want to!

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!”

Land Rover Freelander (2) SD4 190

“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!!!”

“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.”


Simon from Ketteringham

“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.”


James from Callington

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.”


Alan from Coventry

Suzuki Swift 1.3 DDIS 75

“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!”
