Message If you have a dual-pop, you need a specific EPROM for it, because the MAS reads only half the airflow.

Stillen ECU is the same as JWT. Is it the EPROM for dual-pop ? If not, your engine is running very-very lean and it's the reason why you got engine warning (detonation) and under power (too lean, safety maps, but not safety boost because you have an EVC).

Stock boost w/o stock solenoids should be around 7 psi (stock wastegates springs). If you reach 15psi with your EVC off, you may have a vacuum leak.

YES, 15 psi with stock internals is safe... if you have the right EPROM.
