That may eventually be the case, but you have been datalogging wrong. View the video I posted, then log the car properly (in 3rd gear, from 2500 rpm to redline) and come back here with the results ... We can go from there.
I'm on my phone, and not looking at Cobb's specs, but I'm going to guess your target boost is 17 or 17.5 (+/- 1psi). At 19, you are only 1 psi overboosting, but that may very well be due to improper logging.
