ok i got my ITR tuned with vafc2 etc but now have changed to a better flowing filter as the one that was on there was pretty clogged although it was K&N and i tried to clean it well it was still really clogged etc so ive modified my intake pipe a bit made it smoother flowing and put new filter on it and now it flows alot smoother and intake isnt as loud and actually sounds like its breathing and not struggling to suck.. so is this goin to have an effect on the vafc2 tune? or will the vafc2 still only make it suck enough air to match the tune etc? or will it suck more and not match the fuel supply now? any ideas.. thanks heaps..
