Have played with all DFCO enabler/disablers, in/out ramp rates & still can't reduce off throttle fueling enough to get rid of the exhaust POP. Have also gone to OL fueling.

Wide band goes up to lean when going off throttle, but there remains enough unburnt fuel to pop in the exhaust. Have also reduced injector trims.

What else can be done to reduce fuel sooner without going lean upon deceleration?

Here is the current tune file. Thanks in advance
