I noticed the other day that on full throttle I have black smoke coming out the back of the car.
I bough the car a few months ago but it does have a high compression engine with forged pistons and high lift cams etc. would that be down to the way its been mapped etc or should I look at anything? i.e. clean air filters etc. (gruppe M) or worse engine parts?
