Hey DSMer's, I finally got my Wastegate and was wondering for a stage 1 install like what I'm going to have done soon. Is the wastegate already set for 5psi straight from the factory or do I still have to do it and how exactly? What does the 7 on the wastegate stand for? I need clarification. I know that my turbo and housing was already set for the stage 1 install before I recieved it.
