Misfire cylinder 6

Brand new NGK 95706, precision raceworks coils, and plugs gapped at .020. Symptoms present before new parts. One log is rolling into full throttle gradually, which seems to help the breaking up. The other log I went full throttle and it broke up and went into limp mode. Did not have these problems before the tune. Car is FBO, Catless downpipe. 2011 335i n55
