I have a 98 trans am ls1 125 shot. After i run the quarters and get out of it, it starts back firing. what should my timing be? what else should i try?

progressively lift the throttle, that's all. many set-ups get the poping in the exhaust tract when letting off and snapping the TB closed. it's just the remaing unburned gasoline. try going down a hill in low gear, turn the ign off just for second then turn it back on, same thing happens, the unburned fuel is burning off.
