    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.

  • Ross from Winshaw with a Renault Laguna III 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!

    Regarding my Renault Master Van MM33 dCi - I have recently purchased one of these units and am very satisfied with the performance improvement. Thank you.

    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!

    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!
