So I'm very new to the tuner thing, literally got my MPVI3 just yesterday, and I figured I'd start easy, maybe try disabling the MDS on my '07 5.7 Hemi.
I found a tutorial on the HP Tuners Youtube channel and followed it, flashed it onto the truck and decided to see if it had worked.
Well, first thing I noticed was the truck barely wants to start moving....and it also doesn't want to seem to shift now, like it's stuck in 4th gear now or something. I literally only disabled MDS, saved the file, and flashed it onto the truck? I never touched anything else?
One thing I thought odd was how all of these options in the Trans tab are disabled?
Any help would be much appreciated!
