Mazda Diesel Chip Tuning Boxes

Glenn from Saundersfoot with a Mazda CX-7 2.2D 173 said: The chip arrived the next day and was easy to fit after following the instructions. Although there was a difference on the standard setting after "tweaking" or fine tuning the car has all the performance I require. The increase in power especially midrange in 4th/5th and even 6th gear is considerable. As to saving fuel, I'm enjoying the increase in power at the moment, but I can see that I will not have to keep changing down so much. Cheers!

Stefan from Reith bei Seefeld, Austria with a Mazda CX-5 2.2 SKYACTIV-​D 175 said: A very simple and clean "installation" - done in 5 minutes with no tools necessary. Smooth increased performance, ideal for when driving in the mountains here. Keep up your great customer service and the excellent product quality! FOLLOW UP: I am really enjoying the CHIP Express tuning on my other two cars now, a Fiat Doblo 2.0 Multijet 135 and a VW Caddy 2.0 TDI 150. Great and smooth performance yet again!

Brian from Crawley Down with a Mazda 6 MK2 2.2D 180 said: I purchased this in Sept '14 but have waited a few months before writing a review. It's simply brilliant, reasons? (1) Improved fuel consumption under normal driving conditions (2) Noticeable improved flexibility in gears especially at slower speeds (3) Smoother engine (4) Big improvement in performance which, when used doesn't use a huge amount of extra fuel (5) Much improved torque. I got a professional to fit mine (he knew Chip Express products well) and we initially used the default mid-way setting. After trials we settled on the default setting but fine tuned it to maximum. This gave a big improvement on the edge of Traction Control kicking in so there's no stress, just a big overall improvement. Our 2011 Mazda 6 Sport (180) was quite quick anyway but this has made all the difference - more fun, even easier to drive and better fuel consumption. The car feels better for it. I therefore have no hesitation in recommending it. I only wish I'd bought it sooner. Only one tiny downside is it does confuse the average MPG indicator but having carefully checked it, it shows 4 MPG less than is true. For example - shows 46 but is actually 50 - no complaints! Just buy one!

Steve from Port Augusta, Australia with a Mazda BT-50 MK1 3.0D 156 said: Fitted the power chip today, well I am converted! Standard settings as supplied were perfect, lots of low end grunt for towing, great midrange which extends beyond what you actually need. No more turbo lag, now super responsive from 1000 rpm, this is much better for moving trailers or retrieving boats etc, the clutch no longer needs to be slipped to get rpm up to pull the load initially. This is the best upgrade I have done on any vehicle, money well spent! Please submit my feedback so others may benefit. Thanks for such a great product!

Rob from Watford with a Mazda 6 MK3 2.2 SKYACTIV-D 150 said: Just had my chip fitted to my 2015 Mazda 6 150 Sport and it has exceeded well all expectations. It has been fitted on the factory supplied setting and provides excellent acceleration and torque. I will settle for factory setting for now. Impressed!
