Question...does LSE believe a staggered spark timing to be beneficial for power/economy? I was going to test this at GM but never had the chance. My intuition said any benefit real or imagined would be hard to measure, but as I said...I was not able to test.

Craig,

I don't know. I would have expected the interconnected units to use the timing from the primary unit, thus exactly the same. Maybe the display only shows the timing info from the secondary unit, not using it unless the primary unit is off or fails. It is a question I must ask.

I'm willing to bet at a 5 deg retard you are giving up power and fuel economy. Unless you are detonation sensitive, I would expect no more than a 2 deg retard on a 27 deg baseline for a 10 to 1 CR motor. I would be happy with the 3 deg shift.

Yeah, I am tempted to leave the 3 degree retard alone until I have done some testing. I am just slightly over with a 9:1 CR.
