Cheapest 1:1 BOOST Reference Regulator????
Cheapest 1:1 BOOST Reference Regulator???? what is the cheapest way to do 1:1 boost reference on 2002 f-body???? currently have a brand new 340 fuel pump and it loses 1psi fuel pressure for every 1psi of boost, i ran 15psi and melted a piston, i turned the boost down on new motor to 6psi and still losing 6-7psi fuel pressure

4305m here as well. Picked it up from Advance Auto online with a coupon code

James, mine is on my stock rails. Just had to pick up a few fittings and I used the EVAP line as a return.

It is an advisable addition, but no matter what fuel system you have, the engine must be tuned safely to work with any parts that are bolted on to it and around it.

Verdad Gallardo the tune has nothing to do with fuel pressure dropping. the fuel system does.... what is a tune have anything to do with fuel pressure dropping lol
I have 97 98 fuel rails with a return and a 1:1 referance regulator. Works perfect with the evap line as the return to the factory fuel sending unit. Id sell it for $150

I'm running 15psi on a stock regulator for now, and my afr stays at 11.2-11.4 through the entire rpm range even though the fuel pressure is dropping not at the rail, but the working pressure is dropping due to pressure differential at the injector tip.
doesnt matter if the fuel pressure drops. if tuned correctly it will not burn down. i was running 18-20psi on a stock everything non return fuel system with a single 255 pump with stock pump piggy backing (but not hooked up) and meth injection. i didnt have a fuel pressure sensor, never saw the need. yes the fuel pressure will drop. this will only skew the ve % higher in the ve table and keep the injectors open longer. i was running the standard siemens 60lbers. my car was making all of 700rwhp easily. the issue here is the tune.
