What type of pop is it? Is it a back-fire when letting off from full throttle? If so, you're lean and you need a new map.

pull the spark plug and see what it looks like, can help dertermine if its running lean or hot

You might have an air leak in the exhaust.

usually real black means its running rich, if u can try to get a different map and see if that helps

Grab one off of the power commander website. Try out M226-018. That should get you close to where you need to be. Put a new plug in it and do a plug check and see how it looks. If black, you're still rich. If white and popping when you let off full throttle it's lean. If it's yellow-brown you're about right.
