I'm sorry for doing this cause I know this question comes up over and over. I was reading threw some of the related threads and couldn't really find the question. I just want to be sure I how this thing works before I sink 400 bucks into it. My question to you guys is...When you plug the predator in and select the type performance tune you want will that automatically disable the MDS option? I really want to get rid of the MDS cause I hate the way it sounds with the exhaust. I was reading threw the owners manual and it didn't really say anything about the MDS in it. Thank you guys for the help and also for the help on all the other Threads i've posted. I LOVE THIS SITE!!!!

 

It does not automatically disable it but its very easy to do inside the predator menu. Its one of the custom options.

 

Select the tune, then select modify tune, then modify parameters.
Go to MDS, set it to off, then press escape until it asks if you want to install the tune, click yes.
