okay guys im back, yesterday i did install my new walbro 255, running with 1/4 gas in the tank, i did ajust my VE table, and still my fuel pressure drops, some ideas? no DTCS

134784

bad experiences in back times lol

i did change my fuel filter, it was clogged, i did check my fuel pressure again:

idle: 58 psi
moderate speed: 55 psi
WOT: 30psi

i will go with a walbro 255 i just want it can hold a 100 hp...

It is too much gasoline pressure that drops to be a clogged fuel filter, but i will chage it

255lph can hold a 100 nos wet shot with external fuel cell?

I already checked my fuel pressure:

idle: 55psi
Moderate speed: 50psi
WOT: 25psi

I think it's time to update my fuel pump, which do you recommend?

Running rail system with vacuum regulator...

What does "referenced, no referenced and refined" mean? im a noob

I will get the pressure gauge and I will return here to inform you, thanks for your answers

so i have a bad wideband sensor?
