Wondering if some of these guys are not evaluating or making their SOTP in Sport plus. Love to hear some feedback etc. on JB4 with these late model 4.4L motors.
Humm...... I wonder if theres some neutering happening on the M50i's too? The M550s can't launch properly due to BMWs programming, so they will not see big gains in performance from anything right now.
