    With Cobb, that code can be related to the wastegate stiffness. Not necessarily a boost leak.

    pre engine swap i didnt have any issues with boost . they did not adjust the Wgs , just reinstalled the turbos so something is leaking or not working properly now. using the same map as well as i did before in terms of WGDC. Also this is getting worse and worse. As soon as i got the car back it was boosting fine .

    thanks, will send them the link.

    Well just drove 2500 km with the car from sweden to italy through germany, besides an issue with the lpfp feed hose connection that came off all went well. During the whole trip up to italy i have experienced the sporadic low spool and 30ff code. Outside temp always in the range of - 2C and + 2C.
    In italy outside temps went above 5C and suddenly the turbos started boosting correctly over and over again. Could it be a bug in cobb?

    Oil level went down 1/4 in 3000 km.

    I had something somewhat similar happen and it ended up being a diverter valve issue. It took my car forever to throw the P30FF.
