1.08?

Sounds like it has been dynamically tuned!

There is a method of timing these beasts that will set the timing around 
the 1.07-1.08 area.

I did this method to my truck and came up with 1.07. I currently have my 
107AG set to 1.05 (because it is easily measurable and repeatable) and 
it has never ran as good as it does now.
