The tuner I was looking into has tuned a 130i to 281hp at the flywheel ( he doesn't have the dyno) so it's speculation to me. So theoretically my disa swapped 128i should make alittle less power than a tuned 130i due to the restrictive manifolds.m

I have the dips on the powercurve. Should suggest DISA.
I think your engine is restricted by tune, manifold and headers whilst mine is (was) heavily restricted by the tune and also the headers. My headers look exactly the same as the 128i's.
So tell me, the guys who will dyno your car.. Do they also tune? What kind of discussions did you have?
