fuel regulator prob

[missing_nins]

to sifu,

its ok to set my fuel regulator to 4 bar=58psi on my 4g93t and still using stock injector (390cc i think)...or it is 2 high??what is normal setting?

but people said better rich from lean..

check ur plug whether it's running lean or rich.if ur engine is stock,58psi
can be considered high.48psi should be enough.

i think 58psi is too high...try to set 43psi coz u'r running on stock fuel pump...
just my 2cent..

oo..but it is normal if FR i set below 50psi..when i rev at t/b,my FR meter will drop until 45psi..but if i set at 58psi n i rev..it will go up..
