Excellent, I can't wait to see your results. I would be highly surprised if you don't get 20 hp out of this.
Take a look at this post for some dyno results including a 325i 6M:

I was going to wait to post but screw it. I installed my intake over the weekend and am planning on taking my car back to the dyno this Friday. I have to say during my first test drive the car reacted poorly. Shifts were screwy and the low end torque was gone. Now after a few days shifts are back and the off the line response has returned. The DME must have adjusted to the increased air flow. The big difference I notice from the swap though is when the car gets above 3200 rpm. When I stomp on it there seems to be more torque at the higher rpms. I'm assuming that is when the adjusters are opening. When I tested them a week ago the mid range opened around 3,500 rpm. Then the high range opened only under heavy throttle and above 3,800 rpm. I'll post the results this weekend.
Marcello I would definitely give your DME time to adjust before you dyno.
