boost referenced regulator can somebody explain to me how they work ?
you have 3 ports one feed one return and the 3rd one for some sort of switch to trigger the second fuel pump ?

A boost referenced regulator just bumps the fuel pressure at the rails based on amount of boost. A vac line runs to regulator to allow it to adjust to boost/vac pressure. You need a hobbs switch to trigger the second fuel pump.

would it be plug an play or i would have to get the car retuned ?
If the car is tuned now, unless you've changed something there's no need to up your fuel pressure is there?
Pumps and regulators get fuel to the rails. Injectors and the computer determine how much the engine is going to use. Unless you're running so much fuel pressure that it's affecting the injectors ability to open you shouldn't have to do anything.
Were you starving your injectors?

well if you get a FPR with a boost referance and dont want to retune done hook up the vac line and the fuel pressure will stay the same so it depends on how you plan on running it.

You could always run the sensing line from the pressure side of the air induction system before the throttle plate, this way it will only increase fuel pressure when in boost and won't mess with the fuel pressure in vacuum. I was thinking of using the in tank (factory)regulator. Not sure if anyone has tried this..
well he may need the system to just flow more if he is starving the injectors, if that is all he is needing and doesnt want to return right now then he would be fine and could wait to hook the boost reference up once he changes something and has to go get it returned..... he didnt really state why he was needing it.
i was just trying to help him out i have been in the same situation and am not ready for another tune but needed bigger lines and rails as my pressure was droping like crazy when i would get on it since its procharged, now new rails and lines with the regulator with boost reference and didnt need it to be returned as the pressure no longer drops. once i do my head and intake swap i can hook up the vac line and take the car to get retuned with all the good stuff. just letting the OP know its doable without getting the car retuned.
