Has anyone dynoed a car and documented the power loss from pulling 6 degrees of timing and switching to 2 step colder plugs for a big shot?

Efi Live COS5 is your friend to pull timing when you hit the arm switch.

Does that automatically change the spark plugs also? J/k I already know about the custom OS that they offer.

I havent documented it, but I would assume that it would make power levels go down because of the lack of timing. There is a reason that most motors like 26-28 degrees of timing. They make more power. If you only had 20 degrees on it power would be alot less. I would also like to see dyno graphs of it.
