Feedback From Our Ford Focus Customers

Simon from Sherfield-on-Loddon with a Ford Focus MK1 1.8 TDDi 90 said: I have today received the chip and installed it as per instructions. I have to admit that I was sceptical that this little box would be any use for improving my vehicle because of her age and the fact that the current mileage 186,000, but WOW, what a difference it has made, it's like she's brand new again, lots of torque and really smooth power delivery. I am impressed, thank you for giving her a new lease of life!
Mark from Victoria, Australia with a Ford Focus MK3 2.0 TDCi 163 said: Just received my chip for my new 2011 Ford Focus diesel, I am truly impressed by the intelligent reconfiguration of the power curve. Absolutely brilliant low end torque and very linear. Leaving the chip in the standard setting is great, but if you are wanting more BUTA BING BUTA BOOM put the car in sports mode and WOW its fast. I know that there will be greater fuel economy because of the superb low end pulling power which means you do not need to open the throttle as much. Very happy!
Todd from Blackburn with a Ford Focus MK3 2.0 TDCi 185 said: I’ve recently installed a new CHIP Express on my Focus ST 2L diesel.  The initial feedback is very positive – much cleaner throttle response, more thrust through the mid-range and so far a 2% increase in fuel economy even though I’m driving more enthusiastically.  I expect the fuel economy to increase significantly – to date I have only been doing shorter journeys whereas I would normally do 2-3 longer (100 mile +) runs over the course of a week.
Len from Seaford, East Sussex with a Ford Focus MK2 2.0 TDCi Auto 136 said: I was recommended your chips by a friend so looked at the website and read the reviews. I admit I was a little sceptical of all the glowing reports but decided to buy a chip. I have not been disappointed. It was easy to fit (the hardest part for me was finding out how to remove the engine cover - it just pulls off!) and the car immediately felt different; it was smoother, quieter and the increased performance was impressive. On a recent return run from the south coast to the Midlands I got 61mpg at an average speed of 58mph, a good 20% increase on previous trips. I have very happily recommended your product to other diesel owning friends.
Christopher from Bridgend with a Ford Focus MK2 1.8 TDCi 115 said: I have put the chip from yourselves into the car, it was simple and done in minutes. The power I got was great, you could feel the car pick up speed much better and, my fuel to miles has gone up also, thanks.
Andrew from Leicester with a Ford Focus MK2 1.8 TDCi 115 said: I installed your tuning system into a Ford Focus 1.8TDCi (115PS) after reading all the favourable testimonials. I have to say it did not disappoint... I tested it by driving up to Leeds and back which is a 180 mile round trip for me. I would normally expect about 53-55mpg driving @ around 65-70 mph; with the Chip Express installed I achieved 65MPG! That equates to an improvement of around 20%. Extremely easy to install which took about 10 minutes.
John from Winchester with a Ford Focus MK1 1.8 TDDi 90 said: Thought you would like to know that I am really pleased with your tuning module recently bought for the above Focus and fitted today. I appreciate its an old model and an engine no longer used by Ford but if its an example of your products I would not hesitate to buy another for a more modern car.

“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!!!”

“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!”

“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.”

“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.”

“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.”

“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!”
