Which tuners disable MDS on 2012 5.7, please clarify for me?!

[mxerchris]

cant seem to find exactly which tuners can disable the MDS on my 2012 5.7 can someone set me straight. I emailed Superchips and never got a response.
Thanks....

All 3 do to my knowledge. Superchips Bullydog and Diablo.

diablo does. Ive had mine off for weeks, and ive actually gained mpg lol

Diablo InTune used to disable MDS on my 2012, and just like kg93, I've gained mpg since disabling. And, it drives so much better with it off.

My Superchips 3842 does for my 12.

Like the guys said, every tuner available will give you the option to disable MDS.

You know, if guys are getting better mpg with it turned off, that makes me think the whole reason for MDS was to pass emmissions...... Just a thought.

Emissions and CAFE requirements I believe. Like my '14 Camaro SS. If you get an auto trans you have a cylinder deactivation system, the manuals get a 1 to 4 skip shift... So stupid.

Just did it with my DS Trinity on Tuesday to my '14. Huge difference.
