Also, as far as for leaks under the intake manifold that may be a possibility. I did clamp it down but I did purchase a used turbo with lines that seemed too big. |

if you had a leak under manifod you would notice IMMEDIATELY,and it would stall, and your idle log is good.
when i had a under manifold leak with my supercharger i had so much fuel going on that it literally poured liquid fuel from the exhaust |

You didn't get directions for installing the catch can? In your pic the top port is not connected, that seems fundamentally incorrect. We can't troubleshoot this for you if you don't give us more information. Is this can on the PCV line or the CCV side?
-30 STFT does not indicate a leak, the tune is trying to dump fuel into the motor at that point for some reason and the closed loop feedback system is taking the fuel back out (or as much as it can anyway, the max is -29.7%). I think there is either a fat-fingered value in a table or you have a sensor that is feeding bad information to the ECU. The nipple you keep asking about is in a cold air intake upstream of the MAF sensor? If so it won't cause any issues other than letting in air that doesn't get cleaned by the filter. |

When you say the top port is not connected, do you mean the one I circled in red? Or the one at the very top? There's no instructions for installing this so I'm like super confused lol. Just show a pic of my engine bay |

Where do the two ports you do have connected go? I can only see one line in that pic and it looks like it goes to the CCV nipple on the driver side.

The top nipple doesn't go anywhere and has a filter on it, the other side of the catch can is just blocked off. The only hose you see connected is the one being routed.

Ok, so you are venting your crankcase breather to atmosphere. That won't cause your issues. It will make your car stink.
What are you doing on the PCV side? You can't plumb the PCV output to the manifold unless you installed a check valve inline. I still think you have a tune issue. |

The crankcase vent is run upstream of the MAF in stock configuration, so it is always pulling in unmetered air.
