Where to reference boost with rising rate fpr?

[Shane@DBPerformance]

It should be hooked up to the intake manifold where it will see vacuum and boost. You have to unplug the vacuum line from the FPR to actually check/set your base fuel pressure. The fuel pressure is supposed to change with different amounts of vacuum. There isn't vacuum on the i/c pipe side of the throttle bodt, so you don't want to use that as a source.
