i have a 03 z06 that has a stock pump with a boost a pump procharged with a D1.. i am about to put a walbro 400 in with a boost a pump in. so my question is will i need an adjustable fuel pressure reg with boost reference and put a return line or will i be fine the way it is.

i am doing this so i can drive my car and floor it cause right now i am out of fuel.

i plan on next year doing a twin pump with fast rails and dash fuel lines next year.
