Default advice on trouble shooting over boost and under fuel on map 6 - 07-26-2020, 05:50 PM

hey guys, could use a little bit of direction and advice. I've been having an issue with over boost and low air-fuel ratio when under load. tomorrow morning I'm hopping on a dyno for a couple of hours to try and streamline this process a bit. I just want to clarify what exactly I need to watch for in my logs, I'm gonna be playing around with my boost targets. I'm pretty new to this system and up until now I've been bouncing my logs of someone, but tomorrow I'll be mostly on my own. so any help would be appreciated.
