WGDC looks normal (~50-52 range) and no leak code... no codes at all lol so I don't think i'm leaking

The stock CP/DVs might not be responsive enough under WOT at that boost setting, can't forget that stock boost is less than 9 psi (so you're running about double the pressure/stress being put on the OEM bits). I'm not gonna tell you that spending ~$600 on aftermarket DVs + CP is "magically" going to fix the problem. Have you had COBB looks at your logs to see if maybe they know what's going?
