Hey my 2008 335i 6spd manual has been taking longer than usual to build boost after I shift , I recently installed a crappy knock off BOV and could that be the issue? There’s no build leaks but I don’t remember having to wait 2.5 seconds after each shift to start moving again

Are you tuned or stock? A 3rd gear log would be helpful.
Could be a vacuum leak, boost leak (bov not closing properly), boost solenoids etc.

Just on stage 1 mhd, I can make a log later today, thank you

Log from 2.5k rpm to 6k rpm in 3rd gear. Traction control must be off also.

The valve itself has a hole running through it and must be lined up with the hose connected to it (easy to end up misaligned once tightened). Amazingly many of the u-tube videos don't mention this.
