Hi all, I’m new to the group and just bought a 2013 2.2d Sport 175 AWD to use as a tow car. It’s replacing my much loved 2009 2.2 Mazda 6 Sport 185. I’ve noticed the fuel economy is poor in comparison and I’m contemplating a common rail after market chip. Most claim extra torque, BHP and most importantly up to 15% economy gain. 2 questions. Has anyone else used one with positive results and if so is the plug to the common rail easily found? Many thanks.

I used one for a while but have since taken it out as I found I was having issues with diesel contamination in the oil sump due to failed DPF regens. It may not have been the chip but I removed it just in case. I used it for 2 years and the car seemed a bit more responsive but I found the fuel consumption to be the same or worse when set to better performance and in order to get better fuel consumption the performance dropped. I suppose it is common sense to expect higher performance to come at a higher fuel cost but the claims made from these chip companies don't always stand up to scrutiny.

I bought a 2016 2.2 diesel 150bhp at Xmas and was not happy with power so i had it remapped up to 230bhp + extra 100f/lb torque Acceleration a lot quicker and smother Fuel consumption is app.55mpg on motorway at 75 and 45-48 around town. Cost was £200.00 not cheap but i think this is a better solution than plug in chip in long run.
PS my last car was also a Mazda 6 2.2 sport and that was also remapped to extent that i could leave a scooby for dead at lights lol

You are comparing an AWD SUV with a 2wd saloon so it is unlikely the MPG for the CX 5 will match the Mazda 6, also the CX 5 is heavier than the 6

Thanks for the replies. I went for the chip but I wasn’t convinced it was doing anything performance or economy wise so I returned it for a refund. The guys I bought it off were happy to refund.

Highly recommend the remap as i stated above performance is quite a bit better and fuel economy is improved Its a win win situation If its the fuel economy you want then get the remap set to 210 will still see better acceleration and much better fuel.
My car is set at 240bhp and is returning 52-55 at 70mph on motorway 42-46 round town.

How did the remap affect your insurance?
