Got a picture or link to this setup?

I'm still looking.

I think you must have misread what he said,as the oil pump won't shut off mds.The mds is controlled by electrically run solenoids

It was a quick look thru and other things were interrupting.

Will watch it again.

I can tell you this = first time i drove my truck in Tow/Haul Mode and it is noticeably smoother with MDS OFF.

Felt like my 2018 Tundra 5.7L

Not sure if someone else posted about this, but Valvoline makes a brand of synthetic oil called Restore and Protect that literally cleans the internal engine of all carbon deposits after 3 oil changes. The Motor Oil Geek did a few YouTube videos on this and has lab testing and visual evidence to support the claim. I changed my oil with the R&P and at around 4,500 miles, the oil was jet black from all the carbon deposits that it removed. It is only a few more dollars more than regular synthetic oil and I plan to use it going forward. If you are planning on keeping your RAM forever, which a lot of us over 65 do, this might be a great oil to switch to.

The carbon deposits that bother some engines are combustion chamber deposits, and fouling valves, etc. That is more common with direct injected engines, and not common with the Hemi.
Those deposits are best removed with gas treatments, that will loosen and help remove the gunk. I remember having walnut shell cleaning done in the combustion chambers of my Audi back in the 80's. Now a strong fuel treatment will help clean up the soot, carbon.

That is why if you change your oil every 5,000 miles or so, you should not have any deposits build up in your engine. The internals should stay clean.
