ok i will do this next for sure,will put the standard fuel regulator ba on.im sure the fueling wasnt right with this either thing is though i turned the new sard down from 48 psi to 34 psi and the a/f ratio stayed the same. surely the engines ecu should be regulating and controlling the a/f wether the fuelings at 48 or 34 psi ? i have also undone the plus terminal on battery and left it for an hour.
