timing and missfire help

Is there any way to get my idle spark to smooth out instead of jumping around at idle? Also I am still getting some missfire codes randomly and most are while idling so how can I get this to go away? Cause it is causing my TC to not lock at times. Thanks

Set all your spark tables to 28 degrees at idle. That cam should like that or a little more. Also you can expand the window for missfires setting to keep from triggering the code.

Once a smaller and lighter converter is installed, you might have to do this.

In table C5621 I maxed out the 300,400,500,600 and 6.25, 12.5 cells so I will see how that does. I think between the stall and cam that is what is causing is since it is always at idle. As far as timing I think that the stall saver is what is reducing timing at idle. Does this sound right? Cause the spark goes up and down with the loping of the truck.
