i think you labeled your columns wrong. i take it that your A/F ratio is the 4th column and PSI is the 5th?? if so, youre starting a bit lean but then getting rich at ~5000 rpm, which is ok. although it seems then like 2908 rpm is an anomaly - the A/F ratio would have to change drastically between that and 114 rpm later.

as stated earlier I think you labeled your columns wrong but, you arent lean. Low 12's at peak is just fine. Its when you get mid 13's and higher that you need to worry. You could lean out the midrange some your mid to low 11's throughout most of your peak tq area. You could be mid 12's there no problem and pick up some hp and gas mileage.

Yea, you could turn up the boost to 18 psi and still be safe. Your chips are mapped to run 18psi so run it
Especially since you are not holding full boost to redline, which is like a natural saftey device
Since you have the Tial I would guess the boost roll off is due to stock turbo. With those chips you should be seeing at least another 20-30hp/tq.

"13.67 before torque peak is dangerous."
Thats not there to help spool up?
And 152tq is still a good bit from peak tq.
