2013 Challenger RT. Long tube header installer put a custom tune on my car with my Trinity. I tried to Modify the tune to turn MDS on but it's not taking. The modified parameter shows the * that it has been changed but it's clear MDS is not working. I tried twice and installed the tune both times.
Anything I can do or have the tuner person do so that I can turn MDS on and off like I used to be able to do?
Prior to this I was using the canned 93 tune and was able to turn MDS on and off no problem.

I would get a hold of the tuner who did your custom tune and have him put the mds on in your custom tune and make that parameter adjustable. But the other alternativ is you post the last tune written here or send the last tune written to DS support and see if they help you. But i would try first with the shop that did your custom tune.

Thank you AZHEMI. Will do.

Yeah, they may have disabled it outside the normal on/off switch we use in the tool, so no matter what you set it to it will not come on.
