Same situation here. If it helps, according to dyno charts all of those 122hp variants tend to push 130-140bhp in the real world.
Haven't checked what those 150hp puts out in the real world, but I wouldn't be surprised if its the same tune as in CX5 and 6 with 155hp on paper. After all it's the same engine setup.
When my warranty is over I will immediately re-map my 122hp M3 Sedan. Car should feel like completely different car since you'd be able to really benefit from the power on the higher RPM's.
From the factory it seems that power is heavily limited after 4200rpms with stock tune.
