What tune are you running?
Supporting mods: Supersprint Catless DP
HP/TQ #'s (rwhp/ftlb): 611 / 847nM
1/4 mi time (s): no clue, we don't have drag strips here
I have Weistec ECU, downpipe, high flow filter, VTA and large transmission oil pan. It's been a year since my tune so far zero issue and pretty satisfy.
If you're not trying to be the fastest and you just want a good daily that's fast enough, then sure, buy one. A tune only will add about 80hp.
eh not really chasing numbers.
right now my m5 has 610wheel, quick, but nothing crazy.
Potential-wise, the M17x motor is just barely being tapped right now and can likely exceed the N/S BMW series motors.

Benz has always been behind in the aftermarket game vs BMW from a tuning and mod perspective to even aesthetics. As soon as the F8X M's were coming out, there was carbon fiber everywhere LOL.
