Ignition breakup/Bogging/Backfiring

The plugs are about 3 weeks old, my gap is about .29 the boost was at 10psi when the problem arouse because of this i have decreased it back to stock 7psi and its not AS bad. My MAF looks good as new i took it out today. Im thinking its the coilpacks. Car is off the road for winter now so ill work on it here and there on weekends not too worried about it since im not driving it, Ill be pickin up U2N’s set of coilpacks hope that fixes me up.
