Heading back to Vegas Tues
I have two days to do the tuneup and the sensors

Expect it to take you those two full days, particularly if this is the trucks first EGR tune-up.
Just the experience of doing it makes it quicker and easier. And that doesn't take into account having to deal with the amount of soot y going to have to remove.
Good luck.
A bypass filter is an auxiliary filter added to the truck that only filters 2 gallons per minute instead of the the 100% of the filter mounted to your engine. However it filters those 2 gpm to a FAR cleaner state. It cleans far small particles than the full flow filter standard, which means it removes a significant percentage of the soot from the oil.
