They really aren't that bad, they look intimidating with the engine compartment being so full... There is quite a bit that can be done with the cab on fairly easily if your mechanically inclined. There is a flange nut on the bottom of the tube and a bracket with a nut on the top. Just don't get carried away tightening the nut on top that stud is not very big.

It seems to be common for the ebp tube to get stopped up with soot and cause the vgt turbo to act up. Simple cleaning and usually goes back to work.
Ok so little update, I cleaned it all, it's better boost is really fluctuating now, and still make 43 psi on stock no dpf, I checked my back pressure goes between 30-60psi doing 110 right now, I'm gonna get a new ebs today and gonna use as a excuse to treat Karen to a sealed afe filter, cause mine lookin pretty nasty even after cleaning it!
But recently my truck oil temp started creaking up till the fan cools it then starts creeping up, like its -19 right now dojng 110 and it's at 213.8F
And boost is at 18psi ... I'm also curious would my egr be causing this to?

that is getting warmish. high 190s is normal unless you are working it pretty hard.

What is the coolant doing? They should be within 10deg. Ie ect 200f, eot should be no more than 210f. That is running empty. Loaded should be 10-15deg difference. Egr should no effect on oil temps.

You're running warm. I just did a 4 mile hill at-19 and got to 198ect 204eot with a winter front on. 4.30 gears run significantly warmer than 3.73's too.
Lol, I think it's my coolant I had to get 3 coolant lines replaced, I checked my coolant temp, while warming up my coolant temps were 1-5 degrees warmer then my oil temp so I'm thinking my mechanicic put sh** in it there I got cat ELC or something I was running it before it was great never a issue

Check to see if there is anything in between the radiators too. If nothing is in there take a fire hose to the rad and give it a good cleaning. Could be a simple gummed up core.
I got a new senser a couple days ago, the tube is cleaned, but it really didn't help at all, going up small inclines my boost spikes 30 psi easy no load, Taking off lightly I'll make upto 10-15 psi, is there another senser I need to replace? I have zero codes on my dashdaq either and I'm running my spartan tow tune early lock, thabks guys for any replies

Honestly, that seems about normal to me. On the street just driving normal, no trailer, 30 psi is regularly seen on my truck. With a load or pulling an eliminator I am seeing 50psi or maybe a few psi higher.
I do not know what you have done to the truck. Mine has egr and dpf removed. along with no limit intake and cac plumbing.

Are you watching Absolute pressure or Desired? There is a 14-13psi difference between the two.

Didn't realize it was on a stock file at that point.
I used to get between 6-700km a tank hand calculated, I know it's not true but bare with me, my lie oh meter used to say I was gettin 28+mpg now it's saying 8-12mpg, my truck has a air dog 2, afe pro gaurd 7 filter, 4" straight pipe to 7" single stack, 6" lift and 35x12.50x20s but I was still gettin good mileage with all that, and wicked power, my truck lost to my gfs Chevy cruze the other day with my spartan 310 on... I was embarassed that was my first race I've ever lost....

Whats your rail pressure doing at WOT? What is your EBP vs MAP KOEO? Whats the oil like? Coolant on the outside of the degas bottle? Oil in the down pipe? What is your VGT duty cycle at idle and KOEO? Get this and it will help narrow it down a bit.
