There are a number of triggers for PE mode which is what will enable and lower the commanded AFR. On one stock truck tune I saw the PE delay {B3608} was 60 seconds. Would be worth checking that to start with.

One of our Beta testers ealry on found he was running 14.63 at full throttle, I didn't believe it until I saw the tune.
Change B3608 to cure the problem.
