Default stupid question about afr's under boost

i got my car tuned by "the shop" in norwalk, ct. now my concern is this. when i start building boost, my afr's stay around 13.0-13.4 in the mid rpm range, and than higher in the rpm range, they shoot to between 11.4-12.0 depending on the weather. i know humidity and temps play a factor in the tune, i just wanna make sure that this is safe being that im around 8-9 psi as boost starts to build.

kinda need a more clear picture of what your talking about. what I mean is what afr at what psi, also what kinda timing is pulled (if any).

here is kinda the gist of what i go for.

afr--------psi
13--------1
12.6------2
12.2------3
12--------4
11.8------5
11.5------6
11.5------7
11.5------8

(this is not set in stone its just an example, depending on the situation and conditions as well as supporting mods I will at times deviate from this example)

Nevermind. I spoke to paul @ dezod and he explained to me what the tuner did.
