Feedback From Our Fiat Customers

Stephen from Cleckheaton with a Fiat Ducato MK3 2.3 130 Multijet Euro 5 130 said: Just fitted the chip to the motorhome WOW. MAGIC. FANTASTIC. Does what it says on the box. I will definitely recommend to friends and family thanks guys five stars!
Mark from Credigion with a Fiat Qubo 1.3 Multijet 75 said: It's been about a month since I purchased a chip from you. I can say performance has improved and driving has become more relaxed due to this product. I haven't played around with other settings and will probably leave it as set by yourselves, but overall I am more than impressed!
Trevor from Alloue, France with a Fiat Ducato MK3 2.3 130 Multijet said: Your system has transformed our Fiat based Adria motorhome, totally unbelievable! We had got used to its slow progress after 9 years and 98,000 miles but now... WOW. Thank you so much!
Timothy from Teignmouth with a Fiat Ducato MK3 2.3 130 Multijet 130 said: This is my second Ducato based motorhome to be fitted with a CHIP Express system. On both occasions the chip was simple to fit (idiot proof) and made a remarkable difference. I am very satisfied and would recommend this company to anyone for an excellent service!
Les from Salisbury with a Fiat Ducato MK3 2.3 Multijet 130 said: We bought a chip for our Fiat Ducato X250 motorhome in 2011 and were impressed with the much improved torque and economy. We had some very long trips, e.g. all the way to Sicily and back, with no problems. In 2013 we transferred the module to a new Ducato X250, with the same improvements. The vehicle does a steady 31 mpg and is a pleasure to drive. Recently a fault arose and as a precaution we got CHIP Express to test the module. Nothing wrong with it. Excellent customer service (which is a lot more than I can say for Fiat!).
Anthony from Wolverhampton with a Fiat 500 1.3 Multijet 75 said: Many thanks for your fantastic service upgrading my CHIP Express module. The Fiat now drives much better with more low speed torque and throttle response, also better MPG. This is my second CHIP Express tuning module and for the last 30 months I have been saving at least 10% on fuel with excellent performance in my Volvo 2.4 D5. I have no hesitation in recommending your product as it gives great satisfaction and will pay for itself with the fuel saved, thanks again.
Chris from Turriff with a Fiat Ducato MK2 2.0 JTD 84 said: I have recently installed a CHIP Express tuning chip to my Fiat Ducato motorhome. From the outset the technicians at CHIP Express gave me honest impartial advice about the benefits of fitting a quality tuning chip with a program written specifically for my engine. I was told that if I was not satisfied with the results I could return the chip and get a full refund. The technicians assured me that fitting was simple and they would provide photographic step by step instructions and if necessary they would talk me through the installation by phone. I easily installed the chip by following the instructions in under five minutes. It took longer to make the wiring safe and tidy and locate the chip box in a dry place. I then took my motorhome on a 1,380 round trip from Scotland to England. As the trip progressed the engine became smoother and quieter with a noticeable increase in torque, which in turn gave me much better fuel consumption as less throttle was required. I was very pleased with the results which to me appeared as if a bigger more powerful engine had been fitted overnight. A friend of mine is a partner in a taxi firm in Hampshire, he was so impressed with the change in my motorhome's performance and fuel economy he now intends to fit units to all his taxis. I can only thank everyone at CHIP Express for their professionalism and quality product.
Ugur from Turkey with a Fiat Bravo MK2 1.6 Multijet 105 said: I received my order on Monday this week and fitted it to my 2009 Fiat Bravo 1.6 Multijet. The result is amazing! I am absolutely satisfied with the product. I think every conscious diesel engine owner should try Chip Express and experience it for themselves. Thank you for manufacturing such a little miracle.
Frank from London with a Fiat Bravo MK2 1.9 Multijet Sport 150 said: I purchased the CHIP Express tuning box at 2.30pm Tuesday and received it 11.00am the next morning! I installed the box in under 5 minutes and noticed a immediate increase in performance, much more torque and a smoother ride. The engine sounded quiter and feels free reving, the pick up from absolutely no RPM is just amazing. The aftersales is fantastic, CHIP Express were very helpful with any questions I had. Thank you very much indeed!
Ian from Peterhead with a Fiat Fiorino / Qubo 1.3 Multijet 75 said: Excellent! Engine felt choked before and frustratingly sluggish. Engine now revs freely and pulls much harder... brilliant product!
Michael form Chichley with a Fiat Ducato MK3 2.3 Multijet II 130 Euro 6 said: Just to let you know I fitted the box to my new motorhome and the difference is amazing! Fuel range went from 108 miles left yesterday to 150 after fitting. Works perfectly!
Keith from Malvern with a Fiat Ducato MK3 2.3 Multijet II 150 Euro 6 said: I wanted to see how the drive was during our tour of the Scottish highlands from which we have just returned. Certainly the roads there were a good test and I did find the increased torque in particular very beneficial, making driving the motorhome a pleasure as I never felt it was wanting for urge, even in high gears. Your product is excellent and is matched by the good service provided.
Dave from Coulderton with a Fiat Ducato MK3 2.3 Multijet 100 (Motorhome) said: The chip on my 100 Multijet worked wonders. The 100 engine was just that bit small for the motor home but with the chip fitted it made so much difference. It enabled us to cruise comfortably at about 70mph and fuel consumption was better!

What others are saying...

“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.”

“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.”


James from Callington

“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!”

“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!”


Andrew from Lochwinnoch

Land Rover Freelander (2) SD4 190

“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!!!”
