Air Temp vs. AFR

Air Temp vs. AFR
Im in the process of Tuning my Turbo 1st gen, However now that the temps have dropped significantly I need to start correcting. Is there any baseline that i could follow ie. for every 10 degree drop, 10% more fuel.
Not sure if this really makes a difference but these are the Specs:
S4 13BT
Microtech ECU
FMIC
Stock Turbo at 8 PSI for the moment
MSD Race Wires
I've been tuning for mid-low 14's AFR under Vaccum and dropping to 12's up to 6psi, then 11's for 8 psi. Car Pulls Really nice.
Also on a side note: I've been pulling 2 degrees of Timing for every 2 Psi of Boost. Havent had any issues like this, but i'd love some input.
Thanks
