Feedback From Our Dacia Customers

Gordon from Redhill with a Dacia Sandero MK2 1.5 dCi 90 said: I have a 2014 Dacia Sandero Stepway which is fitted with the Renault K9K 1.5dCi 89PS 220Nm engine which is also fitted to some Renault and Nissan vehicles. My previous car was a petrol turbo with 147PS and 210Nm torque so my new lack of power was obvious but as far as torque was concerned I was already 10Nm up in standard form. I had heard about diesel tuning boxes but have to admit I was extremely sceptical about them. Being an ex-racer and ‘old fashioned’ tuner I was used to increasing performance with cylinder head, camshaft, induction and exhaust modifications but as this car was my first diesel I was willing to try this ‘modern gizmo’. I ordered a Chip Express tuning box for my car which arrived the following day. Fitting instructions were comprehensive, easy to understand and tailored for my engine (not like a lot of generic instruction sheets you see). Actual fitting time was less than the time I took reading the instructions…it’s that easy however due to my OCD about engine bay tidiness I took a further 10 minutes making sure everything was neat, tucked away and tidy (but that’s just me). I left the jumpers set as supplied and the performance improvement was immediately noticeable as was the engine noise which was significantly reduced. The engine immediately felt livelier and the torque increase was impressive. It’s difficult to express on paper, you really have to feel it, however, there is a low speed steep hill which I travel up every day. Before ‘the box’ it was an asthmatic 2nd gear hill with the engine getting you there but don’t expect much more. Now, the car will easily pull up the hill in 2nd and will accelerate whilst doing so. That hill sold it for me and told me that the money was well spent. As far as fuel economy is concerned the engine is quite economical in standard form with 60mpg achievable however ‘the box’ made 70mpg easily achievable on my daily commute into London. I have a ScangaugeE device which shows, amongst other things, journey mpg. After a month or so the urge for more grabbed hold of me and following a quick email to the ever so helpful people at Chip Express I was assured that pushing the jumpers to the maximum would have no adverse effect on my engine. Within minutes of receiving that email I was under the bonnet and moving the jumper plug straight away to its maximum position (although I was told to do it in stages). All I can say is ‘impressive’. The hill I mentioned earlier is now a 3rd gear and accelerating hill AND crazy as you may think fuel economy has improved yet again and now 75-77mpg is achievable on my daily commute. The car is a lot more driveable with fewer gear changes and as a result a much more relaxed drive. All in all it’s a great bit of kit and I challenge anyone not to say they’re impressed by the increase in performance.

“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!”

“Just to let you know I have fitted the unit to my Peugeot 407 SW 1.6 down here in the Algarve, where it is warm and sunny, and, as with our Volvo D5 system, simple to fit, the instructions are excellent and it runs beautifully. I initially bought a cheaper unit from another company, but it did not actually work! This is my second Chip Express unit and again the results are remarkable, much better response, a significant increase in power and better economy, in my view an outstanding unit! Thanks again.”

“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.”

“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.”

“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!”
