Turbo needing cleaned?

Here lately I have noticed my truck is feeling a little sluggish compared to normal. I used to be able to hit the gas and be into the 90s when passing just 1 car not meaning to. Here lately it wont do that and feels almost stock like. The truck pulls stronger in the 45-70 mph range then anywhere else. Truck has 218K miles and who knows if its ever been cleaned. Would these symptoms be caused by a dirty turbo?

Your symptoms also sound like a weak HPOP system. You may have a small leak either in the HPOP/oil rails. Over time as the leak gets bigger, you will get the "no start when hot".

Any surging, bucking, missing or stalling at idle?

U0306 - Software Incompatibility with FICM (have you had it replaced recently?)
P0046 - International and they says...."Code P0046 is set when a short to ground, open, or short to power is identified in the VGTCV or wiring between the PCM and VGTCV. This circuit is a continously monitored circuit that takes less than one second to set." ( your VGT plug is ether unplugged or the wiring is chafed)

P0403 - Exhaust Gas Recirculation Circuit Malfunction
P0405 - Exhaust Gas Recirculation Sensor A Circuit Low
The last 2 you can get rid of by plugging your egr valve back in. It doesnt hurt anything to have the valve in and plugged in and it keeps the codes off.

I would check the wiring harness and even unplug the ICP and look in the end to see if there is oil in the plug. If there is its bad again. I know its a pain in the @$$ but it needs to be done. You could try clearing it first to see if it will come back.
