Well it doesnt have an mbc but it does habe apridruve electronic boost controlly which is not adjustable, so im leaning more towards a boost leak because i also reset the ecu and nothing. It has an open source tune on the stock ecu
when the car is cold and i turn it on tere is a loud hissing noise maybe coming from a loose coupling?
Or from the inlet?
