What is your full boost?
I still need to manage my bost via my external wastegate.I have a 15psi spring but no controller at all on it as yet.

I have the impression you really need a electronic controller with external setups.Manual ones dont plumb in right.
The controller plumbs into a line going into the top of the wastegate and another hose goes from compressor to the side of the wastegate. can i tee the top wastegate line off the side wastegate line. I assume so???
Sorry if that sounds confusing,im getting tired.
