Overdrive jumping in and out also very sluggish takeoff

jay.lohr · Post by **jay.lohr** » Wed Mar 30, 2011 12:22 am

I have a 2006 Dodge Durango Limited running the 93 Octane Performance Tune. I cannot get to the transmission settings and the overdrive is jumping in and out constantly. I had transmission checked and all checked out perfect. Also it is very sluggish out of the gate but from bout 45 mph or higher all kinds of power. Can anyone help? Oh and my fuel economy went from 18 to 11.5 from 9r10 when I went to 9r11... I would like it to shift harder but the overdrive thing Im not sure what is going on there.

Apparently our problem isnt very important... I am going to call Summit and return my programmer and purchase the bully dog tuner.

It was posted March 16th... Figure a half of a month is sufficient amount of time to respond....

I see March 30....either way, sorry.
I reply to about 100 posts a day, I occasionally may miss one

Sounds like it may be MDS kicking in and out, try turning it off to see, and if so, I'll make you a new tune with the MDS smoothed.

Thanks

I have MDS off. Ive tried it both ways. I just changed my plugs to Bosch Iradium and it got worse. not sure what else to try.

Just thought I'd chime in here. On my 5.7L 2008 Grand Cherokee I noticed since 9r10 that the MDS is very noticeable when engaging and disengaging. Maybe make a note for the next release to smooth it out for everyone if that's possible. I have seen a couple different posts with people commenting on this issue with MDS.

Mike, What all did you change on that custom tune? And is there a link on how to get the new tune on the predator? Thanks
