Jerking when accelerating slowly

Since I went turbo, anytime when I accelerate slowly the car jerks, not badly, but she hesitates, like she wants to go, but doesn't. There's no loss in rpms or anything.
Also, it only does it when I'm 0-20% on the throttle. The SAFC takes over after 20% with the lo-throttle setting.
I'm thinking it could too rich at base FP. Stock, the car was at 36psi FP. With 12:1 FMU, when to 48psi. Made high, I know, but FMU gives no adjust ability. So with that so much more fuel coming in and no way to tune it, could it just be rich?
Looking at the STFT, seems to be -9% - 8% while driving under 20% throttle, which isn't bad at all, right? So what do you guys think? Thanks.
