I flashed MHD stage 2 on my mostly stock ride (charge pipe replaced). I mostly commute (65)miles a day. Car feels great. I also used BimmerCode to code sport transmission. Such nice quick shifts.
Downpipe is next. But damn, the occasionally burst today and mid 50 degree temps. Wow, traction was an issue down low. I skipped stage 1 since I don’t beat on it and plane to do a fmic and DP.
