anybody heard of this before? was down the pub the other night and a friend of mine with an elise said this is a good way of getting more power from the 6cylinder e46 engines.
im new to the bmw scene and hes a fairly clued up guy and not the sort to give it the usual pub bullsh*t chat.
can anyone confirm this is actually true? and if so what gains can somebody expect and is it worth just doing this mod or is it only worth doing with say a dave f induction kit and a remap?
