I get alot of afterfire, and yeah that is the correct term for **** people lol...
You should not get any while your actually accelerating in gear however if your car is tuned right, I only get afterfire when I am coasting, or when I am off of the throttle completly at low rpms usually. Sometimes when I initially roll into the throttle I will get one pop sound, and in between shifts at WOT like when racing, I get an pop also. So if you do the same thing don't worry about it. If your car sounds like it's breaking up at WOT then worry about it lol.

Perfectly normal. What it is, is when you take you're foot of the gas the first injection cycle or so is still gonna be goin for broke, and all that unburned gas hits you're hot turbo and pops out the back.
