Re: Re-Programming a Multi Displacement Hemi
I've learned to use Tow/Haul mode when I'm driving around town. It changes the shift points, reduces gear searching, and deactivates the MDS. If you're on the highway it will take a while to shift into 4'th gear so I recommend taking it out of Tow/Haul on the onramp.

A few places will flash the PCM for you and disable the MDS for around $350. KRCPerformance.com and BGPerformancePCM.com. Hope this helps.
