what would be to optimum fuel rail pressure for the svo 42s green tops,for the best spray pattern ? i was reading the bosh injectors.com review on pintle injectors and stated that too much fuel pressure to pintle injectors has the reverse effect for fuel atomization....[quote"Excessive pressure will result in either “hosing” or a spray angle that is too large for the targeted area dependent on the pintle profile. " ]

if im running 66psi fuel pressure at idle would it be considered excessivly high and requires to be dropped down ?????

thats what i thought ,ive recently got my fuel gauge recalibrated and it turns out to be 61psi at idle instead of 66psi after readjusting the ifr i got a much better tune ...
