Well I finally have everything buttoned up on my 347 swap. I got it fired up this weekend for the first time. It will surge slightly at idle cold I believe it might be between some timing and fuel cells that might be driving it. I plant to try and get it out some later this week and see how it drives. The big question I have is the injector dead time for my 42lb Ford motorsports injectors. What I have found on the internet is .762 and a .125 offset. I just want to make this is correct before I move on.

I have attached a data log of one of the starts and idling as well as the tune file. If someone would like to take a look and make sure I'm not out in left field that would be great.

you should be able to lock the timing and using testmodes find the idle valve position you want to get a "steady idle" these values are then recorded.
if you look in the tuning videos thread I created I have a 4 part video series [poorly edited at that] covering idle

Yes I have watched those videos numerous times and planned to use them as a reference when I got ready to enable closed loop idle.
I assume I am using the correct injector dead time numbers or is there a different value i should be using.
