'98 E350 7.3L power loss

My night for fun as you can tell in my other post. Also have a '98 E350 with a 7.3L and I am experiencing some serious loss of power on the upper end. I have lost about 10-12 mph on hills, etc. and have recently had diesel injection service replace all injectors and give this truck a clean bill of health. Not hearing turbo spin up as I believe it should, but would this be a cause for this much loss? Vehicle weighs about 15,800lbs but always has. Nothing different other than new injectors to RESOLVE said power loss...cleaned tank, new fuel lines, as well. Thanks!
