The X3 seems to have a very similar motor set up to the '06 330i with 255HP. Do you have a tune that will boost output for the '08 X3 3.0si with no other mods?
if you do this post dyno's
I believe you will see gains in torque in low end, not much in the high end because it is the same ecu as 328i, just more optimized so there is less room for tune improvement
DESI4life10 dynos of disa + AA may be the best example
