Possible Boost Leak

[Bytz]

I'm having a problem with my car (running link v3) at the moment. Idle's fine, timing's dead on, but if I hit the throttle over 3000rpm it will stall when it tries to settle back down. It also blows quite a bit of blue smoke (oil burning) out the exhaust while this happens, and I am seeing over 3 degrees of knock while in boost over 10psi.

I don't think it's a maf clamp problem because I have a vented bov because it was running perfectly on stock settings not even two weeks ago.

I checked my logs and my airflowperrev is around 0.22.

Any ideas?

SOLVED: BASE TIMING WAS OFF

my guess it's your vented BOV.
you need to run speed density or maft to properly use a vented BOV.
or else you get tuning issues.

Blowing blue smoke and knock under boost would come from a vented bov? My car was running fine with it two weeks ago.

Your turbo is dying...

Pretty much a brand new turbo, absolutely no shaft play as well.. checked it.

I did a boost leak test and found out my BISS was allowing air through. I fixed it but I'm still getting the same symptoms.
