Vac Route

[TalonSpeed]

Swapping a 2G stock manifold to a JMF SMIM with 1G TB. Also using JMF MAP adapter to install Omni 4 bar map. How does my Vac routing look?

Personally, I would designate one vac source just for the map. T the boost gauge off a tbody port. Is the "p" port an open vac source?

I could do that. The P port gets Vac and Pressure I think. I could run boost gauge off the P port, and run the BOV off the waste gate hose.

I'd run the BG off the fpr port. Your WG line should only see boost pressure, no vac. So leave your bov line at the p port

Thats right. I forget the BOV needs VAC and Pressure.
