Looks like you may have a vacuum leak to me, considering that it runs rough after it catches itself from the revving. Boost leak test!

Step1 after buying any DSM/vr4- replace anything that's rubber.

I always do a TB rebuild and replace vacuum hoses before anything else! Solve a lot of future problems.

BISS and its O-RING are new. I will do leak test again. Car runs rough because it needs fine tuning as injecters are upgraded.
