Think the throttle is modulating like that to help control your boost. You overshoot a little and the throttle drops a bit to bring it back to target.

What intercooler are you using? Your iats climb pretty quick for a single pull. The dme will usually begin to pull the performance above 120.

You say all you've done is the d pipe. Have you done an upgraded charge pipe yet? They are known to blow at boost below what you are running.

May want to bump up your fol. Your trims are about maxed.
