Try halving the entire start air flow table and set cranking ve to 100
checked fuel pressure after sitting over 12 hours. 48 primed cranking 58. got it to start again and no issues when ran for for at least a min. does have new plugs and wires
Did it have fuel pressure when it had the hard start?
If so.. I'd multply the cranking airflow table by 15-20% +

Please try this and report back.
Flash it, start the truck then, shut it off and let is sit overnight. Try the cold start in the AM and report back.
