Default Cobb Stage 2 07 Sti not reaching target boost (datalog)

07 sti with 40k original miles. Invidia catted DP and full exhaust. Stock intake on 93 oct. Running Cobb stage 2 93 oct. The first log is normal waste gate and the second high waste gate. I pressurized and tested the system for a boost leak and found nothing. I am not sure why I can't hit the 19.5 psi target. The HWG map just barely touches 18 psi but my DAM dropped and I had a light knock. Any ideas what my problem is and how to reach target?
