I haven't messed with timing split a whole lot. I know the closer together the more power, but on the haltech I have heard there is a chance if they are too close together the trailing can fire before the leading, causing a blown motor. There are some ecu's like autronic if i'm not mistaken that have them firing at the same time, and there is no chance for error. The difference in power between firing at the same time and slightly apart is still a mystery to me, never seen any real numbers.

Wow that is low, considering I run 14 degrees after 15psi. Does the car start to break up or something? What kind of igntion system do you have?

When your running no split you will notice timing doesn't like to be to far advanced. I would run about 2~5 degrees at 10 psi boost. Maybe even less depending on your fuel. DON'T RUN 15 degrees timing with no split!!!
