“Superb Skoda - Superb economy! Just to say that I fitted the CHIP Express last weekend and I am now getting 50 MPG on and around town (compared to 44 MPG previously) and a phenomenal 59 MPG on this mornings commute to work (120 mile round trip). Previous average was 46 MPG. I was initially very sceptical about improvement but sensible use of throttle and with unit in default setting I have been blown away by the improvement! I am recommending to friends, work colleagues and family!”

“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!!!”

“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!”

“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.”

“Received the kit for my Honda CR-V this morning - less than 24 hours after I ordered it. Simple, clear instructions. I spent 5 minutes reading through the instructions and it took me just under 10 minutes from start to finish to install the system - and I have no mechanical knowledge or experience, so if I can do it anyone can. Left the setting on the pre-configured mark and went for a test drive and WOW! Immediate and noticeable increase in power and especially torque. Could not resist tweaking it so increased to the next level and went for another test drive. DOUBLE WOW! I am amazed! I think I shall leave it on this setting - it definitely does not need any more! All in all I can recommend this system - it does exactly what it says it will do and it is a simple 10 minute job to install.”
