The boost contorller itself has an arrow on it and i dont konw which way to start hooking up the vacum lines....right now i have it from the arrow to the wastgate and the other side of the TVVC to the turbo...its not doin anything at all...someone told me to go from turbo to wastgate and have that line teed into the TVVC not the arrow side...and the arrow side going directly to the top of the wastgate but when i didt that boost was unmesurable it was at 10psi at like 1/2 thorttle...
