Boost drops from 8psi to 4psi and then back up??
New TRD S/C and NST pulley just installed with WeaponR header. If I am at full throttle I can boost to about 8psi but then it will drop to 4psi, and back to 8psi and back to 4psi???? Any ideas.

you might need to get a stronger by pass valve.. my suggestion get the turbo smart bov dual port kompact serious 25mm, it hold in boost better then stock and gives you the nice bov sound with out stalling your engine

I would go for the Forge 007.
