Update: All the vac lines are good and i replaced anything that looked bad. As far as it being the charge pipe, we tried that the first time i had this issue and determined that it wasn't anything to do with the charge pipe or BOV as the exact same issue was there.
We just switch the power pin on the ecu box from 2 to 8 and what happened was very strange... my boost profile in map 1 which used to be go to 7psi then hesitate and go to 9psi when the compensation was added now goes from 3psi to about 5 psi after compensation.... switched it back to pin 2 and the boost went back to its 7->9 PSI routine... this SCREAMS electrical power issues... connectors are all good and together and i checked the power connector on the procede harness and the connection is soldered very well. it doesn't look like my ECU box is getting all the power it needs...
