Its basically a rod that keeps the wastegate on the turbo closed, the standard actuator gets weak over time and causes weak boost levels.
Its a worthwhile mod but id be looking on replacing the DV with a forge 007p or similar and the pcv system first as if yours is standard then theyl need changing by now.

Take a look around and check out peoples build thread for inspiration  :cool:

Ahh rite a dump valve never clicked on haha, how hards it to fit a forge actuator need fine tuning to it opens and shuts at the correct times?
