Weird poping sound when accelararing

[Newkid]

Ok so I got a bit of a problem..I think my car is misfiring when accelerating. Well especially when the car goes into boost and the car stutters. Can somebody tell me whats going on? Is it time to changed the spark plugs.

Help me! PLz :runaway:

how much boost you running, does it pop after shifting?

Its stock like 5 i think. Im not really sure but when its not on boost the car seems fine but once boost climbs from 0 to five it starts popping and the car stutters:cry:
