Sebz might have said it was ok because it was on my car when he tuned it. With that being said it did nothing to help with the drop in boost, so not sure why he recommended it. Perhaps because you already bought it.

Edit* The AEM is fine if your just trying to control boost level. Ie if your trying to go from 8 psi to 10.

Here is the AEM solenoid
