2011 535 xdrive
Upgraded FMIC and dp

just replaced:

flashed Stage 2+, I see some timing being pulled and turbo ~2 psi lower than target at higher rpms... how unhealthy is the car?

Here is another log. Car has 140k, seems like the turbos are done, or could be just the diverge valve?

Could you upload the log to https://datalogs.spoolstreet.com and copy the BB code from there and paste it as a reply here?

Sorry about that, clearly missed the big top tab that says " Dataogs"

It's normal for the little stock turbo to fall off like that at higher RPMs but it's pulling 6 degrees of timing in some cylinders which isn't good. You might drop down to the stage 2 non + map and see if it gets better. You already did coils and plugs so it might just be too much for the octane. Maybe someone else can chime in

I will do a boost leak test to make sure it’s all good there. Guess I had higher expectations for the stock n55, I was expecting to be targeting higher boost numbers, closer to 16psi, but seems to peak and just die off.

Would a gallon or 2 of e85 help to prevent the timing correction? Might be crappy winter fuel

You're only about 1 psi below target so I don't think there's a boost leak. I think it's normal to run just below target everywhere.

You can try a little E85 or flash the 91oct map but keeping running 93 and see if that helps the timing.
