Having Some Trouble After Installing MM3

[Rich Pockrandt]

Rich P, 2008 Ram 3500 4x4 G56 single wheel stock fueling 35/12.5/18 toyo at2 5in straight pipe mm3 Drd tunes.

So I recently did my spark plug delete and my antivirus software from DRD.

I have about 1000 mile on it since and I am extremely pleased.

I have noticed a couple of problems.

First my Cruise control doesn’t work anymore (it work fine before, I use it a lot).

The second thing is my speedometer is reading about 4 mph higher then I am actually going.

I have tried adjusting tire size in the tuner and it doesn’t seem to make much of a difference if any.

Any ideas would be appreciated.

Sorry you are having trouble, unfortunately I don’t have a fix, but found this post that may be of some help.

I would contact DRD and see what they have to say my friend.

What value are you entering for tire size?

When I did mine it didn’t agree with how I entered it.
