Very Nice! Good move on getting away from the the D-Box as well, it was the reason my first engine blew. Won't be buying anything from Delicious again.

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.
Found the post here:

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?

Thanks so much for that, it was useful to build a wiring harness to run 2 T-maps. 1 in the original runner location for Temperature only and the 2nd in the Remote block from BT (located elsewhere) for Pressure, sourced from the back of the SC.

Just made the changes yesterday.
If last nights test flight was any indication, the ECU likes the slightly lower IAT readings and is allowing more timing advancement.
Then again, it could've been the cooler air... or my fertile imagination.
