Symptoms are bad idle, hesitation at low rpms when tipping in, -30 to -40% fuel trims and p0172. Everything is fine at higher rpms in boost.

Today I installed the remote MAP box (I know, like 3 years late...) and routed the gen 2 bypass valve vacuum actuator to the middle port on the SC nose. Feels a bit peppier in low-mid RPMs, but is that because the bypass valve is mostly closed whenever I'm on the pedal?
