Peter from Falmouth with a Renault Scenic 1.9 dCi 130 said:I'd had my Renault Scenic DCi 130 for 3 years and was getting fed up with its performance and general sluggishness. Got the tuning box from your good selves, fitted it in the dark in about 10 min. What a difference! Makes me smile just thinking back to that first drive. The box has been on the car for about 3 months so far. Economy is up by around 15%. General driveability is excellent on standard setting, mid-range punch is a revelation.
Steve from Morcambe with a Renault Laguna MK2 2.0 dCi 150 said:Just a big thanks for your promptness. Two days from sending my old Citroen C5 II 2.0 HDI 135 chip to receiving it back fully programmed for my new Renault Laguna II 2.0 dCi 150. A brilliant service, the tuning chip works just as claimed. As per the Citroen the Renault is now smoother with much less turbo lag and much more torque. Many thanks!

Ross from Winshaw with a Renault Laguna MK3 2.0 dCi 177 said:I would like to thank you for the excellent service. The difference in performance was massive, my Laguna GT 180 was transformed; I could stay in higher gears at low revs and accelerate much more quickly. I really noticed the difference when I removed the tuning box to sell the car, it felt flat without it. I sent the tuning box back for an upgrade to my new Kia Sportage 2.0 CRDI 136, which is also superb. Turnaround was only a couple of days. The customer service is excellent, I would highly recommend CHIP Express!
Mark from Reading with a Renault Laguna MK3 GT V6 3.0 235 said:I purchased one of your systems for my Renault Laguna GT Sport Tourer 2.0 dCi 175. I was impressed with the car but heard about your product and decided to give it a try. The fitting was simple and I left it on factory settings. Instantly I noticed an increase in power and drivability and with us living in the country the extra overtaking advantage on B roads was worth the price on its own. Four years on I decided to change my car to a Renault Laguna Coupe 3.0 dCi 235 GT and decided that with the extra standard power and torque of the new 3.0 dCi V6 I would not fit a CHIP Express box to my new car, or so I thought! Having taken the chip off of my old Laguna to take it to the dealer for part exchange it was almost like driving a completely different car. The power and smoothness I had taken for granted had gone and I just couldn’t believe the chip had made such a difference. I arrived home with my new car and the first thing I did was contact CHIP Express to arrange to have my chip changed over to the 3.0 dCi. This in itself was a quick and easy process and the new chip was fitted following the excellent photographic instructions. Left on standard settings I did some before and after testing on some quiet country lanes and was amazed. I have had the chip on for over a month now and the wife still wonders what the big grin is about as we drive around. I will never have another diesel car without fitting a chip box and my father was so impressed he has purchased one for his motorhome. Thanks for a great product and service!
“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!”

“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!!!”

“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.”

“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!”

“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.”

“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.”
