looks like I'm not reaching boost Target by around 2 psi both runs, IAT raises pretty high too.

I have ER chargepipe, VRSF 5" Stepped IC, VRSF Catless DP, MHD Stage 2+, and XHP Stage 3. My chargepipe has little wiggle room on the connection to the throttle body. Could that be where I'm leaking? Currently no codes, but I do hear a weird whistle, kinda raspy, in the exhaust when past 50% throttle.
95 with hella humidity. Oklahoma weather sucks
