535i GT boost issue
JB4 installed about a month ago, then ER charge pipe 2 weeks ago. Car has been running great until last night, then I noticed a sound of rushing air beyond 2.5k rpm. The car runs ok, but the power is noticeably limited. I am going to hook up my laptop tomorrow night to check codes, and see if it's making any boost. Seems to me like all the pressure is getting lost. Can anyone give me ideas on what to check before I take it in?

Your charge pipe is clamped down securely?
Is the air sound a boost purge? That would point to your DV. The DV could be dumping boost as a safety issue. Record the sound and post it.
