My ¢¢: very much agree with your decision I would definitely do the same. Even if I was forced to drive 72 vs 75 to have the same RPM as I used to have (I have misophonia and can not tolerate certain sounds) it would totally be worth it to have the jump on somebody in a Corvette from the late 90s. (or really 99% of any car on the road: hell even sub 1L motorcycles).

Are you talking about your M sport or the other (you have two X5 now right?)

5% works out to 25' in a block. If you lose half of the torque gain to drive train variables you'd still be nearly an additional car length farther in a block vs your start point. Think of recent red light showdowns where it was neck n neck or the other guy was just barely sneaking away this upgrade will net you something like a car length per block. I didn't look at time to distance chart but I suspect you'll have already passed 60 mph by that point.

"Pics or it didn't happen". We would love to see a dash cam video
