Problem:
Car leans out(16ish afr) in transition from vac to boost. This is only for a split second then goes to 11ish afr (still not dialed in) to redline.

Basic info:
KA24E
T3 turbo @10psi
550 injectors
Walbro 255
Aeromotive FPR
SAFCII tuned to read MAP for throttle input. High Map kicks in at 0psi. Yes, I could set the low map at zero and high map for 10psi, but first I want to remedy this issue. I've tried to have the high map start before boost to fix this, but to no positive results.

Any advise would be great.
