I went down to Braman BMW in Palm Beach and picked up the X3 after they added the Mass air flow and stage 2 programming. I really like the improvement. The added torque is very noticable. The added 240 rpm's give the car more speed in each gear. Once you are at highway speed the car accelerates much quicker than before. It seems to get better as it adjusted to the new programming on the first day. It was worth the money! the cost was 349.00 for the air unit, 399.00 for the programming and 475.00 for the labor. It is all certified under BMW's warranty. I would recommend it if you are looking for an added blast to your X3 04.05 or 06. You can speak to Eric at Dinan extension 132. I am headed up to NC to go skiing and I am sure I will really enjoy the ride.
