Default deceleration popping

Can someone tell me what to do to get rid of the deceration popping sounds from the exhaust?
I recently had 2.81 pulley, steeda cold air, x3 tune,heat exchanger,also I expected to feel more hp ,but not much different from stock.
Also I have the flowmaster catback system.

that is more than likely a rich condition, the unburned gas is popping in the exhaust...I'd recheck that tune, esp the fuel pressure and timing and the 02 sensors...good luck

more hp from what original setup? do you have cats? every mustang i've ever heard pops at one time or another - popping and a small backfiring sound is different. if it wasn't doing it before all the changes, go get your tune rechecked

Is there a setting on the x3 tuner that I can look for to reset?

You know what, now that I think of it mine used to pop allot under deceleration in gear. Since the tune, it no longer does it. Ha! I never noticed, rofl.
