AA vs BPC throttle response
I have a stock (save for CDV delete) 2011 128i Sport 6MT N51. It's my DD but sees track time occasionally.
There are numerous threads about the different tunes available for these cars. However, most threads seem focused on power and torque curves. What I am interested in is improving throttle response. Is there a significant difference in throttle response and overall drivability between the AA and BPC tunes?
