Richard from Christchurch with a John Deere 6330 4.5 4V R4 CR 105 said: I just have to write to let you know how much better my JOHN DEERE 6330 tractor is running now your chip is fitted. The power upgrade is astounding and I can now pull heavy loads without changing down so much. I would recommend your company to any farmer with confidence. Cheers!
Adrian from Jondaryan, Australia with a John Deere 9770 STS 9.0 R6 360 said: Just to let you know I fitted a CHIP Express to my JD 9770 Combine with excellent results, more power and less fuel (8 to 10 litres/hr) making harvesting a lot easier under difficult conditions. I have had the unit over 12 months now without any problems. The chip is priced very well compared to other brands. Thank you very much!
Tim from Tewkesbury with a John Deere 6630 6.8 4V R6 said: Fitted first to a John Deere 6630. It transformed this tractor from 125hp up to 157hp. So now have two more on my John Deere 7530s and it takes them to well over the 220hp - all for no extra fuel. Great service from Chip Express - answered my questions before purchasing and sent it out very promptly. Thank you. Everyone should get one, or two!
Tim from Thefford with a John Deere 7450 Harvester 13.5 R6 said: I would like to the time and say how fast and brilliant your service has been. I run three of your units and have been very pleased with them. Many thanks again.
Warren from Lockrose, Australia with a John Deere 8130 9.0 R6 215 said: After recent floods devastated our farm we had to re-level all the paddocks. We purchased a 3 meter wide laser bucket to pull behind our John Deere 8130. After spending many hours of working the tractor on the farm and levelling we were very disappointed in the performance of the tractor. There was no torque what so ever at below 1500 RPM and no power. We had to work it in the 1700 to 2000 RPM range this meant constantly changing gears and riding the clutch under load. Fuel consumption was up to 36 litres per hour. After fitting your chip the torque and power from 1300 RPM up was incredible and fuel consumption was max 25 litres per hour plus working in higher gears we are very happy with your product. It was easy to fit just like you said and has made it a good machine to operate.

“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!!!”

“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 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!”

Land Rover Freelander (2) SD4 190

“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.”

“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.”

“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!”
