I wrote the MSD support tech about the additional 30 degrees of initial timing and they are stumped. They thought that my distributor wiring is backwards but that checks out. They also thought that my two distributor wires were touching one of the coil wires or one of my spark plug wires. I re-routed the pickup wires and insulated them inside of a rubber hose to make sure that they are not getting any interference, but I won't be able to start the car back up until late this weekend. The tech never commented on the two timing lights that I am using.

Any other thoughts on the extra timing at idle?

Thanks
