    At about 4pm yesterday I ordered a chip for my brand new Vauxhall Antara, it promptly arrived at 11am this morning and took less then 5 minutes to fit, now that's what I call service! Car already feels smoother (auto box changes gears without me knowing) and the drive is now transformed, just as promised, 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!

    Just wanted to pass on my thanks, Chip Express is a fantastic product! I used to loathe driving my Frontera, but now I love it, I can not wait to get driving it. The formerly gutless motor now has power and torque I didn’t know it was even capable of producing. Driveability has increased 10 fold, the pre-chipped motor only had a small amount of power between 2000- 3000 rpm and just had no power past 3000rpm, now with Chip Express it pulls like a train right the way through the rev range up to 5000rpm limit, and the low-down torque is unbelievable! Fitting was simple and took 5 minutes, no problem. Fuel economy has definitely improved, although I have not quite worked out exact figures yet, but I will get to that. Another thing is that the engine now sounds and runs perfectly, it’s very smooth, even on idle. I will be recommending your product to everyone I know with a diesel car, I am just sooo impressed with this product. Thanks again guys!

    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!

  • Frazer from Gwent with a Vauxhall Insignia 2.0 CDTI EcoFLEX 130 said:

    I have had my Chip Express fitted for about 6 months now to my Insignia 130ps EcoFLEX. Instant power increase and getting on average 56 miles to the gallon even with my heavy right foot!! I have been meaning to play around with the fine tuning settings for a while but only just got round to it yesterday. MY GOD what an even bigger difference... the car pulls like a freight train in 5th and 6th gears now and acceleration in 3rd and 4th is awesome!!! No extra smoke or soot and runs really smooth still. Thanks Frazer

  • Craig from Milton Keynes with a Vauxhall Astra 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!

  • Shaun from Thetford with a Vauxhall Astra 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!

  • Ian from Burton Upon Trent with a Vauxhall Vivaro 1.6 CDTi Biturbo 140 said:

    My new 2015 Vivaro is running great, the throttle response is improved, RPM's now climb faster and fuel consumption has been reduced. So all in all a happy customer and many thanks to yourselves!

  • James from Gloucester with a Vauxhall Astra 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!

  • Ian from Fishcross with a Vauxhall Antara 2.2 CDTI 163 said:

    Very easy to install on my 2015 model, took me less than ten minutes. What a difference! All round improvement, money well spent. Thank you Chip Express!

    Hi guys, it's me again with a red face. Here's a good tip, don't try a fit a chip on an icy car when it's freezing cold and your fingers are as flexible as lead pipes. Go for a drive to warm the car up, leave it 5 minutes and have a cup of good old tea to warm the hands, then hey presto the chip will fit first time. Just been for a drive with the system fitted and WOW it is very impressive, it sounds quieter, feels smoother and the performance is terrific. Well done!
