Looks like everything I need.to make the change , Tuner is included so i can turn the MDS off in the ecm
Make idle adjustments etc etc

Free shipping so $1525 plus tax delivered to my door , other than oil it looks like everything I need to do this MDS delete update
He recommends at a bare minimum cleaning / inspecting or replacing the oil pump and maybe even the VVT solenoid


Thoughts ?

what cam? I would replace timing set&oil pump,flush out all the oil passages,as they will have metal in them from the lifter&cam.

Stock grind 5.7 cam , just non MDS specs

Im planning to change oil pump. VVT solenoid and timing set while its apart. As I really only want to do this once

Tuner has capabilities of several different tunes / programming settings

The filter catches the metal before it goes into the passages unless you run Fram filters... in that case shame on you!

The only reason to delete MDS is if your going to a bigger cam...

Make sure that is an actual mopar cam not the Chinese copy for sale all over the place for dirt cheap, they are awful!

Thanks,
Its confirmed, A New Mopar non MDS cam , and new mopar Scat pack NON mds hemi lifters

I believe its this one https://www.summitracing.com/parts/mop-53022263af/make/ram/model/1500/year/2012#overview

Im after long term reliability . Not make it a race car . So stock is just fine
And it seems its overwhelming to delete the MDS system for long term life in one of these engines. Combined with a quality full synthetic oil and high quality filter

Its my daily driver and used to pull a trailer 2 or 3 times a year

Brings up the question. If I delete the MDS.
Do I still keep using 5W20 oil. or switch to something a little heavier ?

Keep using 5-20,if you don't your ch engine will come on.I have delated mds on 7 vehicles everybody says no difference in fuel millage .

There's no backing to the MDS causing issues claims. It was never an issue in the earlier new Hemis and both MDS and non MDS lifters can fail. But it's probably the route to go when you're already in there.

I agree, there is exactly zero evidence the MDS causes the lifter failure trouble. I do cams in manual cars and 5.7 ram 2500s all the time and the don't have MDS. The pre 2009 engines had MDS with basically zero lifter and cam failure and ironically they had an even lower volume oil pump so that theory goes out the window also. I have done enough cams in these to build a log cabin with them and never had to do one before 2009. I actually see less MDS lifters go bad than non MDS lifters in engines that have both, perhaps because the lifter is not experiencing high spring pressure every other revolution... they only have installed spring pressure wearing out the roller when the system is engaged while the normal lifters are cycling thru low spring pressure and maximum spring pressure.

When the MDS solenoid is replaced with the plastic plug you get more oil to the lifter sides that is not useful and this in turn means less oil for rod and main bearings that is useful. Those MDS solenoids actually give the bottom end more oil when it is under a load and needs it the most.
