Got some knock from the leaner AFR by solving part of my boost leak issue. Changed all the crappy hose clamps but I think my Forge BPV may be leaking with the blue spring so I am planning to swap in the red spring.

Rob will clean from the AFR's once I get a new map but I still need to fix something...

Fixed the issue by swapping my 3 Bar MAP sensor with a CS 3.5 Bar MAP & a shorter bolt.
The stock bolt may have been bottoming out and not held the sensor in all the way... or the sensor was crap.

Car pulls hard to redline, logs attached for anyone who is curious.

This is after:
1. Rerouting 3-port EBC - improved responsiveness
2. Boost testing intercooler + piping - Found big leaks, swapped many hose clamps
3. taking apart VTCS bar - found missing plastic o-ring and replaced it
4. Installed red spring on BPV (Forge V2)

Thank you to everyone who helped with suggesting things.
