Just recently had my 750Li tuned by SMS here in Atlanta, just wanted to share since I'm seeing all these n63tu post. Car has a muffler delete, and still had my charcoal filters on when it was tuned. (Not sure if Charcoal filters really make a diff in hp or not) Anyways, The car made 100whp and 93 trq to the wheels over stock with the SMS tune. This was all done on a Mustang dyno, in about 65 degree weather. May do e-cutouts and ********* next. Enjoy!
