I always hated mds, but I just couldn't justify a tune for a while. Anyways as typical with all these hemis, the pcv had sent so much oil into my intake and I decided to pull my manifold, clean it and regasket it. I read somewhere on here that installing the plugs without a non-mds cam would cause problems, but leaving them in and unplugged would be fine. So while I was cleaning my intake manifold on my truck I said screw it and unplugged em.
That gave me a cel because of course it would. It convinced me to finally get an unlocked ECU and a tuner. I have mds disabled in my tune and I've never had any problems.
Is it totally possible that I misread something and could have just put in the block off plugs? Of course it is. Do I care enough to pull my intake manifold off again to replace the solenoids with block off plugs? No way haha.
Besides, it's like an egr delete, if it's unplugged, it's effectively blocked off the same as a plate would do.
With the tune, did you bump the engine idle up~750rpms?
From what I've learned here in the RAMforum, lower rpms at idle are supposedly harder on the cam/lifters due to lower volume of oil "splash".
