MSD set ups

Rat Patrol,
why is the ignition curve going down and not flat?
This is not that much ignition at all. I set my peak at 30° @ 3000 I guess.

Did you noticed a change in acceleration? In combination with the MAP signal maybe?
And finally, what octane your fuel has? We here in germany doesn't have lower than 95 in our fuel. :) But can go up to 102. If required. :)
