check bbv is closed with engine off, top port connected to top of sc inlet port, lower bbv actuator port open to air or connected to the oem bbv solenoid.
if bbv is closing and a sc belt is present then im gonna guess you need to double check your MAP sensor part number.
as well as the bin file, a 1 bar os will never see boost, a 1 bar os with a 2 bar map will have ****ed up load calc's as the mapo sensor tells it the MAPressure is lower than it is, it will run but not like it till it learns.
a 2 bar os with a 1 bar map will show boost under higher throttle openings, even on an NA engine. load calcs will be way off, run rich
a 2 bar os with 2 bar map will show boost as it should if the sc is working with correct load calc's
im gonna gues that's not a two bar/GTP OSID bin, or someone just copied 2 bar settings into a 1 bar bin's MAP tables, without properly changing all the rest.
