Default break up during deceleration

I am experiencing popping noises when I decelerate by letting off the accel pedal. I am running 850cc on a t3/t4 turbo. I know that it doesnt have to be running that rich; what would be the best approach to get a smoother decel?

first make sure your TPS is calibrated properly
you can next reduce the amount of fuel in the decel columns
if that doesnt fix it, add timing so the "charge" isnt igniting while the exhaust valves are open.

The TPS is good.

By the decel columns, you mean the higher rpm, low map? Got it.
