I don't see any CPI bins here:

...but it does list some 5 speed bins you could use compare tool in tprt to make changes. Was BBNT a CPI bin?
Perhaps looking at other mask that list CPI bins and you modify from there. Make sure you use appropriate corresponding xdf/adx with whichever mask you might try.
