Most linear and factory like and pulls almost as hard. It's down about 0.3mph on the 1/8th mile vs stage 1 so not a big difference. My car also had K&N drop in filter, charge pipe, and intercooler.

I put the M2 map on last month and are mighty impressed just like you said. It is a great map if you like linear, high-reving driving styles rather than low end with lots of torque. I have much more fun having to wring out the power - at least for street driving..

I am running an LSD with the final drive ratio changed from 3.08 to 3.46 in my M235i. The M2 map fits perfectly with the character of the car. The final drive ratio of the original M2 was also 3.46 for 6 MT, btw. With the change I can fully experience and hear the engine closer to legal speed limits

In terms of linearity it feels almost naturally aspirated. Can only recommend to give it a try.
