the proper definition of backfiring is a burp back out through the inlet. how this happens is a fault within the ignition or cam timing which results in a plug being fired whilst an inlet valve is open. -bang...
have one big enough,you can blow plenums apart,and such. LPG cars are notorious for it if not setup correctly,with quite spectacular results.

a pop in the exhaust from exhausted unburnt fuel cooking off is also referred to as backfiring,but the first definition is more widely recognised.

it's one of those words that keep getting used even though it's wrong, like diff ratio, it makes sense to everything but in actual fact there's no such thing as a diff ratio - it's actually a final drive ratio, it's like saying the KAAZ centre has a ratio, but in actual fact it's the crownwheel etc

The issue could just be that it's overly rich in the tune at higher revs, and the fuel isn't getting burnt until later on in the exhaust
