Why do turbos backfire?
The combustion gases keep the turbocharger spinning when the engine is not delivering enough exhaust gas.

This unburnt fuel, when ignited by contact with hot surfaces, causes the backfire.
What causes popping in an engine?
When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. When combustion doesn’t happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise.
