Turbo needing cleaned?

[legionxxii]

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?

What boost numbers are you seeing?

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".

Need to pull codes that will tell you exactly is there is an under or over boost situation.

Driving at 70mph boost is 4-6 at WOT around 26-28 running x race non studded. Codes are p0046, p0403, p0405, p2287 and uo306. Egr is deleted also.

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.

What can I use to clean it

Electrical connector cleaner. The one I used was arisol.
