Lean AF at peak torque

Hello all.
noticed that my air/fuel ratio is high as high 12's right before peak torque(whish is around 3800-3900K rpm) then drops gradually to 10's.
I am working on leaning out the higher RPM but should I also worry about lower RPM range, esp low 3000-4000rpm, near peak torque?

no, it's not tuned. i got ecu+ and ecuflash cable so i am trying to tune by myself.
I am just wondering if that's 'normal' for everyone(high AF ratio around peak torque) or should i target for AF ratio of mid 11's at all rpm range under WOT.

11.2 just before peak torque on 91 seems to be a safe bet at about 20-21psi.....
