Okay, first off I did the search and cant come up with what I am trying to figure out. I have a 2005 2wd that I am wanting to lift and put bigger tires on. But I cant find a tuner or anything to correct the speedometer. So if anyone has found anything that can help me I would appreciate it a lot.

wow i feel retarded now. Just making sure, but that works for the 4.7 too right?

 

You can take it to the dealer and have them adjust it too...

 

I have heard that the dealer cant do it past a certain size tire. Do you know if that is true either?

 

Website says for all '98-'07 diesel & gas trucks. I would imagine you just can'tupgrade it to a flashpaq as it doesn't support the 4.7L.

 

On a 2005 the dealer can do it by revolutions per mile. If the dealer you go to doesn't know how to do this, call me and I will explain this simple task....
