My truck was going into limp mode. It was saying “Engine Power Reduced”. Could my EFI Live programmer need to be reprogrammed ? My fuel filter was loose and since I tightened it it has not gone into limp mode. My truck does have 400,000 miles on it .

No, you shouldn’t need any updates. You were probably sucking air into the fuel system if your fuel filter was loose. If it hasn’t happened since you tightened it, I’d say you fixed the problem.
