Filter, can't see the point in a freer flowing one if it is going to let warmer air in sooner losing power just to gain higher less usable peak power and probably let crap into the engine at the same time.
Pipe, still open to one of these for sound if it isn't overly loud.
Remap, was on the fence but decided against it for precisely all that kerfuffle you went through on yours 24v, if any engine related problems were to arise I wouldn't want to put the blame on the map, doesn't seem worth it.
On a slight tangent... still mod related
Would a remap be needed when increasing the engine capacity?
Performance cams, what are the cons of these, do you lose torque in order to gain hp, from what I've seen peak power is much higher in the revs, same midrange power?
