Are vernier pully's really worth having if you have megajolt.

I know MJ controls ignition and the pully controls valve timing but given the control offered by MJ is it worth having a VP too or not.

Is the OEM pully likely to be that far out??

It will always be better using verniers to get the best from your cams, but you can always fit them at a later date and use the standard ones for now.
It is more important if the cams are not standard.

If you are keeping originl cam probably not worth it. If you are using an uprated cam then timing is necessary to optimise valve events due to extended durations.
