Who's tuning your car? just for reference. If you still have the factory boost pressure sensor installed, id say remove it.

yes, just run the vac line from the TB or ICpipe right to the wastegate and that sould end your boost cut (if you have the boost pressure sensor still)

i have a vac line off the ic pipe to a manual boost controller then to the waste gate... that sounds right... right?
