It will.
BMW won't make a transmission that only have 10% margin of failure.
Because with CP itself, there is about 5% increase of horsepower to the transmission.
I would worry about the drive shaft first before the transmission.
I have seem a few with aggressive tune and R compound tires, twisted that drive shaft like a tooth pick.
