It's pretty easy to get the balance shaft 180 degrees out of phase if you don't know what you're doing.

I cant watch the video because Im at work but Im experiancing very similar symptoms. My car vibrates, shakes, rattles above 4k and feel very diffrent then it used to. This was all after my 60K service was done.

Looks like I should of done it myself

 

its ur balance shaft belt, im positive, just take it back to the people that did it and tell them ur balance shaft belt is 180 degrees out of phase. The shop re did mine today and its better than ever!

Hello everybody!

I have the same story but on different specs:
EVO-IX, 2.3l, AMS ballance shaft removal kit(!), M2 cams...
Noise from 3 till 4.5k at any load
I'd like to believe that is is "balance shaft belt is 180 degrees out of phase" but I do not know how to do it wrong without ballance shaft???
Help me please!!!
