Hey guys this is my first post to the forum. Not a pleasant one, sorry. I just bought an 07 Speed3 and it always felt kind of slow and I feel like the reason may have been a boost leak. I bought an accessport to look at the logs and my boost levels don't hit the 16PSI target for stage 1 COBB OTS tune. The car is bone stock except for the stage1 tune. Hopefully someone more knowledgeable than me can look at the logs and point me in the right direction. Thank you!

it sounds like you have a boost leak buddy, i think the best course of action would be to buy a frs/brz/86 (turbo and thus boost leak free). feels bad

PS. Kiruba thinks your under utilized.

Looking at the time from 1.47 to 1.63, you can observe how the mass airflow jumps up by a lot. That mean your air input is inconsistent. Similarly you psi sensor might have some few issues. A quick fix may be to stop being underutilized
