This explains my impressions after test driving the M2 comp. I have an OG M2 with a BM3 stage 1 tune but was considering switching to the comp. After test driving the M2 comp I was actually surprised. I was expecting to feel a tangible change in performance (notably high-rev power delivery) but it actually felt underwhelming and slower than my OG M2. I guess the stage 1 tune with that instant torque kick makes a big difference! Don't get me wrong, the S55 in the M2 comp has a lot more tuning potential, but I'll stick with my OG until the next gen M2/M4
thanks for sharing.
