WHat other things do you have on the motor? Injectors anything? Also do you have the BOV hooked up correctly. Vaccum leak will cause the motor to die. If you wired everything correctly then its most likely not in the SAFC.

Im no longer running SAFC but you might try pulling some fuel out of the curve and see how it reacts. Just go to low throttle and pull fuel out from idle up to 1500 rpms. Not a lot of fuel but a couple percent and see if it acts different.
