I have also read similar comments between v2.03 and v3.01 on which one felt more powerful, at this point I will stick to v2.03 not just because it feels more powerful but I have not observed the carbon build up.
It appears that I am experiencing the same on my exhaust tips. Didn't really notice it till the other day, +7 days on the map S1 Sport v401. What could be the cause? Should I be concerned?
