Feedback From Our Kia Customers

Bruce form Winchburgh with a Kia Sorento MK1 2.5 CRDI 140 said: Thank you very much for your excellent and rapid customer service,if only more company's had your work ethics. My upgraded box arrived today, it was fitted in the usual 5 minutes and the settings straight out the box are absolutely spot on. I think this is my fourth box and I would recommend this product to anyone, it is the number one mod for a turbo diesel. Apart from the increase in performance, improved fuel economy and driveability there is now the added advantage of buying a lower powered version of your car and then to fit the CHIP Express box for the same if not better performance then the higher powered model without the burden of the higher road tax. Thanks once again for your sterling service, only rivaled by the outstanding quality of your product.
Geoffrey from Warnbro, Australia with a Kia Sorento MK2 2.2 CRDI 197 said: Just wanted to say that I am truly impressed. I was sceptical about how this would help my Sorrento. But straight away noticed more power when taking off and much smoother gear changes on the auto. It has also smoothed out my downshifts when slowing down (the main reason I wanted it). The Kia was a little sluggish and the 1st gear to 2nd gear change was a little harsh, now this has made the car just awesome. Have kept it on standard settings and am very happy with the gear change improvement and power improvement. Thanks guys!
Jim from York with a Kia Ceed MK1 1.6 CRDI 115 said: You may be interested to know that with the tuning box disconnected the best local running mpg was 50, where as with the unit connected it is normal for me to see 55/56mpg. It does better on long runs when I have seen up to 60mpg cruising at 70mph. Many thanks!
Ron from Thetford with a Kia Sportage MK3 1.7 CRDI 116 said: 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!
Adrian from Huddersfield with a Kia Pro Cee'd MK1 1.6 CRDI 115 said: I recently purchased a 2010 Kia Pro Cee'd only to discover it had the detuned 115PS 1.6 CRDI engine which felt flat compared to the 126PS 1.6 CRDI model my partner owns. I have now fitted a CHIP Express tuning box and the car has been transformed. The acceleration and mid range torque is greatly improved and it now feels lively unlike before. Overtaking is much improved as is 3rd gear acceleration, which is especially useful on slip roads when joining fast moving traffic. I have yet to check the overall MPG change but so far it would seem less fuel is being used. Thanks very much!
Frank from Leicester with a Kia Sorento MK3 2.2 CRDI 200PS said: Just fitted my chip and WOW I am seeing a marked improvement in both performance and economy. From 29 mpg up to 42 mpg! It is pulling my 1800kg Caravan really well.
John from Grimsby with a Kia Ceed MK2 1.6 CRDI 126 said: I have now fitted my orignal chip to my third Kia Cee'd 2014 126PS SW, before this I had a Kia Cee'd 1.6 90PS and then a Cee'd SW 115PS. Before refitting I ran the car towing a caravan and town and distance runs for about two months. I have now fitted the chip and once again the car is transformed. When towing I used to have to gear change twice on small inclines, now I dont have to change gear at all, the car just pulls away on hills. The fuel average is considerably more, the engine runs smoother and the performance is like having a 2ltr. Thanks to your staff for sorting me out!
Doug in Sydney, Australia with a Kia Sportage MK3 2.0 CRDI 185 said: In short I have been delighted with the results. The standard program gave a definite increase in smooth torque delivery and power but on the higher settings the car has been utterly transformed. I have every reason to attest to the published performance improvements. The vehicle feels like a V8 now! An effortless surging wave of torque and power throughout the rev range with no increase in fuel consumption. My wife absolutely loves it and will not even consider going back to stock mapping. I cannot recommend this product highly enough. Less than 5 minutes to install, incredible performance increases with no increase in fuel consumption - you'd be crazy not to get this for your Kia. Best wishes from a happy down under customer.
Frank from Leicester with a Kia Sorento MK3 2.2 CRDI 200PS said: I have just been on a sixty mile trip with your chip fitted and averaged 44 .9 mpg, for a big car like a Sorento that’s pretty good. Prior to this I removed the chip for a service and the economy dropped down considerably, it also reminded me how poor on economy (and take off) the car was without tuning. As soon as I put the chip back on it was a better car again. Thank you so much!
Bruce from Broxburn with a Kia Sportage MK2 2.0 CRDI 140 said: I fitted your system to my 2006 Sportage, it has transformed the car. Incredibly while towing a caravan I managed to return 5mpg more then my brothers slightly newer but identical Sportage!
Neil from Berwick-upon-Tweed with a Kia Optima 1.7 CRDi 136 said: I have had the chip fitted for a month and now done approx. 3000 miles having just returned from a trip to Cornwall from Scotland. To say I am impressed would be an understatement. The car itself is quite rare on the UK roads and the acceleration has turned a few BMW and Audi drivers heads, a few asking what engine is under the bonnet? On a long run the fuel consumption was in the high 50s to low 60s - impressive. I have been driving for over 60 years and driven many different vehicles however to improve the performance of a standard engine by simply fitting a little box is outstanding. My son-in-law is a Kia Tech and said after taking it for a test run that if they fitted them in the factory they would sell many more cars. Recommended: YES!
Clayton from Queensland, Australia with a Kia Sorento MK2 2.2 CRDI 197 said: After a very simple and easy fit (two weeks and around 2000Km later) I can only say how happy and surprised I am with the results I have experienced from your product. The performance increase feels to be in line with the figures you quote and the fuel economy so far works out to be around a 12-14% improvement over the non fitted figure. As a result of this I would highly recommend your product to anyone that may be contemplating an upgrade for their diesel!
Darren from Sheffield with a Kia Ceed MK1 1.6 CRDI 115 said: Just bought a chip for my kia Ceed diesel automatic, a 2008 model. I have just done a comparison test before and after. Throttle is now much sharper the engine is smoother, the turbo seems to carry on giving stronger boost further up the rev range. I did a 10 mile round trip-before the chip, average 50.1mpg, after the chip average 56.3 mpg. I now have a smoother, faster and more economical cruiser. Thanks from a happy customer!

What others are saying...

“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

Citroen C6 2.7 HDi 204

“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!”


Edwin from Bridgend

Ford Kuga MK2 2.0 TDCi 163

“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!!!”


Ian from Manchester

Audi A6 MK4 3.0 BiTDI 313

“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

“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

“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!”
