He's using ls7s I'm pretty sure.

try this i guess, i wouldnt know why you have trouble turning on the vehicle everything seems "fine" to an extent. added some airflow and edited tables.

Edit: i used green top ford 42 injector data... lol let me see if i can edit this file with ls7 data

That's kind of my thoughts. I'll check over your revision in a few. I've really been thinking its a mechanical problem. The throttle blade has been messed with. I have set the blade where the IAC falls close to 140. The IAC counts really won't move appropriately IMO. Tried replacing it, and same thing. Any other ideas?

Tune looks pretty good. Any reason why ltfts are disabled though?

since you were previously running rich, it would want to take out fuel so in this case if the fueling is a little close, the ltft's would remove fueling and with the file i gave you would make it run lean to an extent.
