I have no cat and my car RARELY pops on deceleration. I think I may have a problem?

I don't think so, if things are working correctly the ECU turns off the fuel on decel and without unburned fuel it's not going to pop.
 
Ok good to know, the wideband reads --- so that seems like what it's doing. My father's Vette pops like crazy so I wonder why its still injecting fuel. Anyways thanks for that :)

Others cars do different things, can't say what the corvette does.

On a DSM if the idle position switch doesn't work the ECU doesn't know that the throttle is closed and it doesn't go into decel fuel cut.

My idle switch is broken/disconnected so I checked the "simulate idle switch from TPS" box in link. Does the disconnected idle switch affect that?
 
DSMLink also does different things depending on how you configure it. If you select simulate idle switch from TPS it will behave close to how the real idle switch works. There are also additional setting for decel fuel cut that make a difference. They call it coasting FC offset where FC means Fuel Cut.
 
If you like pops, you can always just throw in some negative timing in the 3k+ rpm range for low loads. Just watch those exhaust valves ROFL
