hi iv got a 1.8 n16 and its now time to do some tuning. Where is best to start?? I'm considering uprating the manifold and having an induction kit fitted, has anybody else done these and noticed a nice increase in sound/bhp. Also considering a remap. anyone had that done? is there any companies anybody would recommend? might get mij performance to do the exhaust as iv heard they are good? thanks guys!
