Have you seen the sticky in the technical section re 320i engines?

Sprint booster will not overcome the 'flatspots' when your engine shuts down at motorway speeds!

Only cure is to sell it and buy a diesel...

Oh and in BMW magazine they did s piece on a Japanese 320i customer who supercharged his, didn't seem to be worth it IMHO .

Good luck

My previous motor was a 320i SE auto, I used to use the Steptronic a lot in order to keep the revs up, where the power always seemed to be, which suggested perhaps the 320i is best suited with a manual gearbox.
It always seemed to fly at the speed limit!
On the autobahn (of course) I could be at at 105+ mph and still accelerating very nicely!
I always thought it was quite a nice engine, smooth & quite with little road noise I suppost due to the narrower tyres compared with the 320D M-Sport.
Passengers were always surprised as to how quite the car was.
