Any cat guys on here? LEE troubleshooting

[Hetdiesel]

Well I installed new cam and crank sensors took the truck for a ride still fludders like the injector. it only seems to do it when it's hot ,loaded and on a hill like fuel starving. So I put a gauge on it still good fuel psi no drop when missing/ shuddering occurs. Im not getting any faults or logged events starting to drive me crazy. And now the twin we have to this truck is doing the same. Wouldn't The intake valve actuators cause a fault some how?
