Figuring out possible boost leak with datalog?

Here is my datalog of my 3rd gear WOT pull. I have a basic understanding of how to read it, but I'm not sure how they relate to each other

Backstory: My OEM chargepipe blew, so I replaced it with a VRSF chargepipe. After initial install, the new chargepipe slipped off again because I didn't tighten it down enough. After putting it back together again, I am having loss in low end torque or hesitation around 2500-3000rpm

I got a fuel pump code when the new chargepipe slipped off, but i've gotten it before and they just go away after clearing codes. From what I've read online, it sounds like the LPFP is going, but it doesn't look like it in my datalogs

Please correct me if i'm wrong

if wgdc is climbing and boost is falling, it's an indicator of a boost leak.
yours looks fine.


those timing pulls though, that is costing you a fair amount of power. walnut blast, check gap on plugs, other maintenance. fix that pull and you'll have another 30hp on tap.

Okay I'll definitely look into that. Was there anything in the log that specifically relates to loss in low end power?
