I have read the same thing about the correction limits, and I've seen both 20% and 25%.
My 2.7 runs on a 3.4L tune at-17% long term fuel trim without issue and afr is spot on.
I would assume that if all other components are left stock (intake and exhaust), a 2.7 would run around -15% on a 3.2 tune.
