Installed Burger Tuning PBX in 2010 x3 xdrive
Seeing as BMW wouldn't do anything about the hesitation from a standstill & when accelerating from low speeds I decided to install a tuner. The Burger Tuning PBX fixed things up just fine. It wasn't too bad to install (was a bit freaked out pulling the ECM out) & definitely takes longer than the manual if you've never done one. The default "lag fix" program took care of the hesitation. Recommend it to anyone who's frustrated with the low speed drivability.
