Sport package pushes limiter to 155
I have had three 7s in the past 6 years. All with the sport package and all limited to 155. This latest one has the M package and picked it up through ED. I had the car humming over 150 with room to spare.
The dealer can reprogram it to 155 or in your case 149 they just are not obligated. Best thing is to buddy up with one of the techs in the shop and see if he/she would do it.
The whole purpose of the sport or M package is pushing the limiter higher (149-155) plus the little things like suspension and black trim.
We only need a second to make a mistake.
