Well, the 617 manual isn't that forgiving.
The normal range is:
22-24 kilopascals or 320-350 psi
minimum is 15 kpascals or 220psi
Permissible variance between any two cylinders is 3 kpascals or roughly 45psi.
I've got a maximum deviation of about 70psi with a deviation of 30psi or so between the other cylinders and the low one.
Oh and now I find the torque spec for the injector lines is 25Nm. I hope I didn't overtighten them. One of the throttle linkage mounts in the valve cover stripped out.
