What is a safe afr

[J-Z]

for a 10psi boosted 09 rt challenger. at wot, she starts out at 10:1 and stays there till 3000 rpm. at that point she climbs to 11:1 at 3800 and then climbs to 12 at 4400 and goes to 12.7 from 4500 to red line. Any ideas if this is ok.

I don't think 12.7 is good even without boost.
