Drivetrain R56 Wastegate open
#3
#4
Find a new mechanic that knows current BMW operation. He is traditionally correct, most off-the-shelf aftermarket turbochargers use default-closed wastegates with calibrated springs to open at a certain boost pressure, however this has limited control even with an EBC.
BMW chooses to operate their turbo engines with a default wastegate-open situation, and a vacuum pump is computer controlled and pulls the wastegate shut depending on operating conditions and driver input. It will only pull the wastegate shut when enough torque is requested the engine operates with boost.
I hope that helps,
Ryan
