You can gain on the order of 40hp with the 3 stage intake, a tune, and headers. You should check out the 128i part of the technical forum. The intake and tune should get on the order of 25-30 hp, taking you up to about the 128i in the 330i. To go higher headers seems like the right path - with a different tune.
