Fuel pressure question

Also 45 psi is fuel pressure under boost, at idle I have 35 psi. Wideband monitoring is need though to keep an eye on things.

any updates on this? i am interested in your outcome because i just upgraded to a walboro 255 fuel pump and i checked mine at idle and i got 34 at idle with the vacuum line on and 38 with it off. pretty close to what the manual says.

i haven't checked it under boost yet so i am wanting to see what an average out come under boost would be.
