I have the stock s13 SR20DET intake manifold. I have a standalone ECU with a MAP sensor integrated into the unit. The stock manifold only has 3 vacuum sources. The brake booster (On rear plenum), FPR and BOV (On throttle body). I am running a brake booster delete kit running on pure hydraulics...

I searched the FSM aswell as the internet but it's always drawn over. Anyone?
