Help: P29CD with OFT stage 0

Hi there, semi-noob here.

I added an OpenFlash Table (OFT) to me 2008 335i E93 about a year ago and started getting misfires. Took my car in and got new plugs and walnut blasting after shop inspected it and it was fine for about 6 months, drove beautifully.

Then, one night out cruising with my girl I rolled the throttle on at about 3k rpms and it misfired. She loved that! Anyway, it continued to misfire under load and for a couple weeks and threw the code P29CD, which was the code it threw before getting the work done.

I datalogged the misfire before flashing back to stock. here it is:

Can anyone look at this and help me firgure it out? is it possible the OFT boost mapping is too agressive? I know it ramps really high at mid range.

Thanks!

Thanks. Not doubting your are right, but anyone with other opinions based on looking at the datalog?

Car has had all injectors and coils replaced by BMW in the past, but maybe bad again?
