Looking for some help on issue, I have 2007 e92 335i rwd manual that I use for drifting. Has mhd 2+, intercooler, downpipes, and charge pipe with bov. During last run of day last weekend I heard a pop that sounded like exhaust blew off then minor loss of power, no cel on dash. Got of track and kind of sounded like turbo was grinding then went away, Came home pulled downpipes and turbos seemed fine, all charge pipes and exhaust seem secure.
I've attached logs from last 2 runs hopefully someone can point me in right direction. Thanks for any assistance.

Still haven't figured this out. I got another set of logs today pulls up to 6k rpm. Anybody see anything wrong here, car seems good and powerful. Any help is appreciated

In the first log (first post) there are instances where its very lean under boost, also rail pressure low

yes I was thinking hpfp but my latest logs from yesterday rail pressure looked ok

Yeah nothing wrong with rail pressure at all as long as it's 1500psi+ @ wot

Only thing i'd be concerned about is the intake temps in the first log your seeing over 180 degrees F. Are you running a decent intercooler? Timing reduces dew to those Hi-temps.

The logs from “yesterday “ look ok, but not the log in the first post. Could be intermittent

yes seems intermittent the pop sound has me concerned, car has 7in vrsf stepped intercooler, downpipes, muffler delete, charge pipes, csf aluminum radiator and dual oil coolers currently running stage 2+ mhd
