Apologies if this has been asked before, but has anyone fitted the above 'plug and play' chip?
I don't do a lot of mileage, averaging 7000 per year, and the majority of my driving is around town, and journeys averaging 50 mile total.
I'm not sure if this would be worthwhile me getting one.

I have allot of experience with piggy back electronics but on motorcycles mostly, there are allot of people out there writing bullshit that they are repeating after read it elsewhere.

I did not investigated this specific device but number one rule to separate form good is to see where is the device
suppose to connect, if it is connected to a sensor only avoid it! if it is connected to the injectors loom then it can indicate that this device has a compensation map inside that re adjusting the fueling, now the question is who done the map and did they use a car slimier to yours to build it.

Usually a device with a fuel map in it cost more then stated on pro diesel chip web site.

Thanks for the reply. I'll check it out.
