As vauxhall is a gm subsidary i've looked it upon one of the american cars that has a similar system. First thing to do is check the duct work for ANY airleaks with soapy water. The clamps that hold htis on are special clamps an dcan't be replaced with any tpe clamp and they must be torqued right. You also have to check for a blocked exaust if you have a scan tool that can operate TC bypass solenoid and TCwastegate solenoid then get back with me and i'll send theinstructins for a Chevy. This has to be very similar. The sensor that controls this is IAT 2 included is a pick of air intake sensor
