The other half has a 2.0 dci Qashqai, and we were wondering about the benefits (or not) of plugging in one of these diesel tuning chips you see advertised in Autocar etc. While we are not looking for a major performance hike, it would be nice if we could get some of the claimed improvements (smoother torque curve etc.) and perhaps a bit of an improvement in the mpg.
Anyone had any experience of these chips? Part of the problem is choosing between the variety available - all of them include testimonials from lots of "satisfied customers", but not sure whether to believe them or not. Here are some examples. Are these reputable companies? All advice will be welcomed.
