The return fuel system I’m running has an FMU that has a boost line attached to it. I want to add the MBC but not sure where to put it, before the FMU or after the FMU? I’m also thinking of removing the FMU altogether and tuning for boost just from PCM.

This is the MBC I want to get if it will work well.

this is my engine bay, the big silver thing on the left is the FMU:

Ok, i am just guessing that the MBC would be best suited before the FMU. The FMU needs to read the info after the MBC modifys the signal. Possible good theory?
