Steve from Morcambe with a Renault Laguna MK3 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 III 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!
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.
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!
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!
“Your customer service, speed at which you deal with questions and chip (most importantly) are second to none. This is the 3rd variation of the chip that I have run, not only do I see the fuel savings made each and every time I fill up but I also feel the changes in the increased performance too. Far too often people only feel the need to leave negative feedback on a product, it's very rare that people take the time to leave positive comments however on this occasion I feel compelled to do so. A brilliant product and one that I highly recommend should you want to make the most of your cars potential performance and make a fuel saving to add into the bargain. What's not to like?! It's been a pleasure dealing with the team at Chip Express, I just wish everyone I dealt with in life was this professional! Thank you.”

“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.”

“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!”

“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.”
