I have a s14.5 and its running around 17 on the air fuel gauge and on throttle it goes to about 15-16. The car dies on deceleration so I moved the maf and it helped until 6k revs. But then I noticed the air fuel so I parked it. My fpr is 38psi at idle and I have a complete build list below. Unknown fuel pump. Should I order a walbrow 255 ? And what fuel pressure should it be at? I don't wanna order a enthalpy tune or parts without suggestions or help and I have a new z32 maf on way
