When you find out let me know...lol
I have the same tool and have been too lazy to mess with it. Trucks running good and I believe in, if it ain't broke...Don't fix it..!
:D
I have the GM 6.2 Book but I question if the numbers would work better from a 6.5 since I'm running a 4911 pump and a Turbo.

Did you ever figure anything out? I know this thread is dead but i'm currently trying to figure this out for myself.

I have it at 3* btdc now... not a lot of rattle and good power with my set up.. but my motor isn't close to stock, lots of fuel & air feeding it..
