ECS vacuum hose allows for relocation of wastegate vacuum controls. Features a silicone hose and 6061-T6 aluminum tap for wastegate controls. Make Model Submodel Engine BMW: E60: 535i: N54 3.0L: BMW: E60:TiAL Wastegate Vacuum Hose Connections. On closer inspection, it originates from a T-Piece in the N75 to VNT Actuator Line. The connector looks like it's designed to also serve as a one-way valve (to close the open line), however when testing the line between the N75 and VNT Actuator it will not hold a vacuum it's leaking from this connector. Therefore no vacuum = no turbo.Unplugging the pressure line to the wastegate will definitely up the pressure, but I wouldn't recommend that. If ya want more boost you either need a different wastegate or a different turbo.
