The whole thing has to be designed/programmed to work together, incl boost pressure.
Is the FPR plumbed correctly? Are you boosting your brake booster?

The entire system has been in this configuration for 5+ years. Yes, I am boosting the brake booster but I have already choked off the hose and saw no difference.

Gasoline is fresh - 93 octane normally from Chevron.
