The engine has tried to stall multiple times but hasn't. Right before it usually stalled the RPM'S would hang on 800 and the engine would have a weird sound. The rpm dip is still there but the Mustang has a dip in rpms also. I'm using the time that stalled a lot right now, its my best tune though since the AFR is almost perfect.
Also found out why my wideband is no longer working, when the tire place lifted the car the lift pushed on my cats and it pushed the sensor into the transmission support. My fault for placing it at a bad angle.
