Worked great for me. I couldn't wait for the 1500 mile mark because I babied it during the break in and it was real sluggish. Even my wife noticed it did not have the pep of my 335i. Which I thought was interesting because it has the same exact engine except I Dinanized the 335i.
So I reset it at 880 mile mark and wow. Throttle response was the first thing I noticed.
Still taking it easy for the most part. But at 1500 everybody better look out.
