    Hey I bought an adjustable fuel pressure reg a year or so back, no model numbers on it I apologize,

    but it was about 179$ and black. Two in, one out,

    My question is are the fuel pressure regulators rising rate or linear?

    I just want to know before I dyno cause I need a linear one to get the best tune.

    Unless you hook up the boost reference port, the fuel pressure will stay constant. If you hook up the boost reference port (assuming this is a boosted application), fuel pressure will raise 1:1 with boost.
