Ready to race!
I have APR K04 kit with the latest tune. Recently I've noticed a problem with hitting specified boost levels before 4k rpm.
It feels and sounds as if the diverter valve constantly opens and closes so I can't hit the specified levels. On the boost gauge the needle tingles at the same position, but everything seems fine after 4k.
I've recently changed the diverter valve, so that can't be the problem.
I don't think it is a boost leak, since I see standard boost readings after 4k.
But I don't know what else could be causing the problem.
I've attached an excel file with the log, and highlighted the the 3rd gear pull.

Would appreciate any help or input
