Is my car misfiring? (video)

I am having a hard timing telling if the car is misfiring, I think it is, however, all 4 injectors spray, and 4 all coils spark. My autometer boost gauge, greddy e01, and haltech map, all have the same read out. My vacuum is about 10-11, I have 272 cams, NO IACV and the idle at the moment is usually around 1400, but a a very steady 1400.

 

Reasons I think it's misfiring

 

1) Light sound of a wrx (known for misfire on sr20s)

2) My autometer tachometer is cutting in and out, and it is wired using a MSD tach adapter, which senses PULSE on the 12 volt wire that supplies power to the coils
