From your codes it also seems like you have a evap leak somewhere too. I’d check all those connections out too
okay that’s exactly what I am going to do, I cleared the codes but the codes for Evap & vac leak remain. The codes for speed sensors went away. I will be dropping it off to my mechanic in the next few days I will update with You soon

Does this truck have a fuel pump control module?

Truck with those will request less fuel pressure until more is needed. That is what the injector flow rate tables are scaled the way they are.

Has any of the calibration been changed for the upgrades done yet?
