stock boost pressure should be 9psi, not 5. Another thing i was wondering is how is that 1 boost controller is controlling the + pressure to both wastegates on both turbos. Where did you hook a boost guage to make your final decision that it was down to only 5 psi? Most of this is just not making any sense.
