You won't get any more power (or at least no more than 5-10) with any tune.
The one in the X3 has all the intake "goodies", and a "less restrictive" exhaust (which actually gives it 5 more hp than the same engine in the 2006 330i sedan). the "3.0si" on the front fenders indicates this version of the engine.

The one in the E92 is the simplified one with more hp than the "2.5" but less than the "3.0" (in the 2006 cars) due to re-tuning the engine exclusively for non-fancy-intake.

All those engines for the US/CA market are 3L (except for the CA 2.3L).
