August 15, 201510 yr Am i correct in thinking idle fuel pressure should be around 41psi? Mine is at 51psi for some reason..... Usually sits at 41psi. Not sure what has changed except the bigger bore exhaust I've fitted.

Mine is running a bit high for idle at 48psi. But I remember john Dixon fiddling with the fuel pump ecu and actually disconnecting it. I'm Sure he knows what he was doing.... It idles well and I've never had any hesitation or splutter. Afr shows 17ish at idle which is lean???
