Engine bogging down with any swift throttle change

I've never had a problem with this, especially with Haltech systems.
I blame this on a badly tuned fuel map (at idle).

how does a poor fuelling map translate to 2-3 psi fluctuations at 10-15psi @ 11:1 AFRs? note i mentioned it wasn't a common problem but something i have noticed before on a few cars. if the cars were misfiring due to overly rich conditions in the sub 10's i would tend to agree.
