I just put it on. The boost guage does not show boost, but does go from a vacume of -20 to almost zero. It is boosting but the tires lit so quikly I may not have saw it show boost.

The problem is this, Do I still need a vacume line on the FPR, or does the FMU sort of replace it. Right now I have a line on both, and the fuel guage don't go any further than it used to 42psi. This may go hand in hand with the fact that I am not yet showing boost? Well I have a stumble at low rpms? Sluggish. It I slowly go to 2500rpms, at 2500 it clears out, then when I hit it OMG
