  1. Street Mode (Auto) - Street Mode (Custom)

    General Challenger Discussion
    Hello, for reference I have a 2019 Scatpack with the A8 transmission. Quite a bit of a frustrating topic as of spent hours and hours trying to look up the unspoken street mode. I've gone through the Owners manual and the SRT performance pages manual both of which have very little explanation of...
  2. 5.7 Hemi Mds lifter problems

    Challenger Issues & Problems
    Alright so we are all familiar with the mds system. It puts your v8 into a v4 mode when not pressing on gas to save you gas. So my car has been making this rottle noise when mds kicks in. It sounds like when you go back the chain of a bicycle. So i’ve researched it and I believe it might be a...
  3. 392 MDS issue?

    2015 to Current R/T Scat Pack 392
    Hey guys, Im new here and just made the jump from a 2017 R/T 5.7 to a 2018 R/T scatpak 392, both of which have MDS. What I noticed and am concerned about is that the 5.7 was much more MDS friendly, in the sense that it would engage as soon as it could and stay on for as long as possible. The 392...
  4. 2016 Challenger auto - Do I have MDS

    General Challenger Discussion
    I ask because all the other MDS posts on here seem to be about the pre-2015 redesign, and also because I'm interested in Borla mufflers and the company's site is asking if I have a 2015-17 Challenger R/T 5.7 auto (yup) WITH or WITHOUT MDS, so... I guess it's not always on-board? Sorry if this...
  5. MDS disable question

    Tuning/Data
    I see a lot of times that people with the Diablo are disabling the multi displacement feature on the cars. Personally, I have no problem losing 4 cylinders while coasting down hill or cruising on the freeway if it saves me some money on MPG. Yeah, it does change the sound a bit but for daily...
  6. Clicking when Coasting

    Challenger Issues & Problems
    My 2010 R/T was purchased 2 weeks ago with about 69k miles on her. When I'm coasting from about 40 to 20 it makes a clicking noise almost like putting a playing card in your bicycle spokes and stop exactly at 20mph. The dealership say it's part of my mds system but I don't think it is.
  7. MDS Disable-Eliminate

    Tuning/Data
    Hi, Just a thought-this can probably only be answered by techs an engineers but I will ask anyway. Does anyone know if a PCM from a manual equipped Dodge Challenger can be swapped in to an automatic equipped Dodge Challenger and as a result eliminate the MDS system? Automatics have a seperate...
  8. Mds shutoff

    Dodge Challenger R/T Specific
    I know there have already been threads posted about this but none I found were specific to my problem. I want to shut off mds but buying a tuner isn't an option for me, I called Chrysler but they told me they couldn't do it (liability thing?) and I don't want to run a heavier weight oil in the...
