Hey guys new to data logging. Boost, not hitting boost target. Getting a 2f6c 30ff code with half ce at around 5/6k rpm. This log shows that.

I saw cyl 1,3,5 timing cor? Dip just prior to when I assumed the ce light came on. Any help appreciated.

Thanks. Waiting on Ken, seems like business is booming for him... Hoping it's just his base map, but we'll see. I cant afford any more surprises with this car!

Chasing a gremlin now.. Lol.
Not sure what's happened. Changed lpfp and coils. Thought ngk plugs looked good. Per my tuner I used protool and reset engine adaptations. Flashed and drove car for 30 minutes before log. Had cyl 6 misfire again at 6200 or so and super knock cyl 1 and 5.
I have a known good set of NGK 2 step colder plugs I plan to install to see if that cures the misfire...
