Well I have to say that I am one hapy camper right now. I just got my tuner all instaled and got the MDS shut off. It was a two-for-one special as far as I can see. I for one and most important got the MDS shut off so there is no more drone noise and for two I am getting about 13+mpg so far after just my usual commuting around town where as up until now I have never goten any better than 10.5mpg for teh same commute. And I have to say that I was driving with a heavier foot than usualy to boot. Oh wait make that a three-fer I have to say that the truck also shifts much better.

 

So are the SC's. He's got an unsupported PCM revision. All the tuner companies run into it with Chrysler products, they change things constantly. The 04s were a nightmare from what I understand, mulitple PCMs from two different manufacturers even.

If someone gets online with them, they usually have a download for it in about 7-10 days after they get the info they need...

 

Instant update at Diablosport with no waiting. My cal id was wrong, updated and programmed the truck in less than 15min. No 7 to 10 days.

 

does my 2008 4x4 4dr big horn have the MSD system on it. if it is which tuner is the right one for my truck. tanks phil allen

 

If it's a 1500 and it has the Hemi, it has MDS. Lotsa folks like the Diablosport.
