I love the AA stage 2 tune in my 08 328i E92 6MT. I also have an '08 X3 3.0si autobox. I just figured out it has the N52 motor with the 3 stage intake manifold. BMW rated output is 260HP. 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?
