what is the recommended injector pop pressure increase for running WVO?

Thanks----------Robert

A late reply, but I'm using the maximum setting for the turbo diesel injectors in my '82. It seems to run a little better. I cut a shim from the side of a coke can to put on top of the spring and it was just right.

Now that is probably the first useful information I've seen as far as thickness for shims.
