Leaning out under load

Leaning out under load
General tuning question..
I'm running a microtech ecu, got a tII w/a hybrid turbo. 720 primaries and 1000 secondaries. RB full exhaust.
Cruising, it runs fine, but under load it leans out. Seems anything close to boost causes the afr's to go thru the roof.
The weird thing is that I've got the fuel curve for load the load map way up, so I'm wondering if, in general, there are any other maps that affect the fuel settings under load?

i would also make sure the fuel pressure regulator is on a nipple that sees vacuum AND boost, not all of the nipples on the intake do. easiest way is to tee the boost gauge in there. if the FPR doesn't see boost, it wont raise the fuel pressure, and the car will be way lean no matter what
