Rawze's EGR tuneup

[Hennessy]

Just wanted to say thank you for posting those videos! Very helpful as I will be tackling that same set up in a few days. Questions that I may have.

When cleaning the parts, how did you clean the inside of the tubes? Carb/choke cleaner or carb/choke cleaner with a brush?

Do you recommend replacing all the sensors with new ones or are there sensors that i can just clean and get away with? What sensors would they be?

On the Peterbilt, you didn't clean the EGR Valve, but should I attempt to clean when doing the EGR Tuneup?

I have a Kenworth T660, ISX15 CM2350 with 757447 Miles. In frame was done at 650000 (ish) Miles with a new turbo and actuator about 4 months ago. Unplugged the (magic) plug just to get me back to Tennessee, so I can work on it. still derated at 25%, But no stop engine code, so I'm thankful.
