Feedback From Our JCB Customers

Richard from Moreton-in-Marsh with a JCB Fastrac 2155 6.7 162 said: I can’t tell you how impressed I am with your product. It has completely transformed our 2155 Fastrac. In 2014, I purchased one of the very last new 2155 Fastracs because it was £4,000 cheaper than the 2170. Both tractors are 100% identical except for the ECU, which determines the horsepower differences. Without the chip, the tractor would struggle up hill. As I’d start to go up it, I’d have to change down gears to keep the engine revs above 1,500 RPM. With the chip, I can forget ever having to miss out all of the 5th gears! The hill in question is on the A3400, just south of Long Compton. It is a 1.25 miles drag of about 1:10. Also impressive is that the engine now has far more torque sub 1,500 RPM. I must admit as to having been very sceptical about chips. I am over the moon about it. As I am sure, is all the traffic that used to get stuck behind me!

What others are saying...

“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.”

“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!!!”

“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 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!”

“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.”

“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.”
