im trying to get this shit all squared away so bare with me

OK so my current set up is ISIS intake manifold, and i have no idea what kind of throttle body i have heres a pic

ANYWAYS, there are 2 vacuum metal tubes that come off the intake manifold right below the throttle body, and theres 1 metal vacuum tube that comes off the throttle body itself (not visible in picture)..

anyways is the metal vacuum tube that comes off the throttle body at constant pressure? is that where i hook my FPR up too?

i hooked up my FPR to that with a T to my boost gauge, and its reading 0 psi at idle, and when i rev it, it drops around -15 or something like that

the 2 metal vacuum tubes on my intake manifold, 1 runs to bov, and the other runs to actuator

let me know if this is the correct way!

hopefully that all made sense..
