The adds for the U7130 for the 03-05 trucks claim that you can adjust the speedo for tire size with the programer. I cannot for the life of me find the information on this site or any other. Can someone please clear this up for an 04.5 HO truck? Thanks in advance!

 

no u cant adjust it thats y i didnt buy one was about to pick one up this weekend and had to call diablo just make sure and they said u can not do it on 03-04.5 trucks u can do it on 05 and up


nice huh

 

Well that stinks. Can someone with a Smarty do it for me without compromising their tuner? Meaning, can you only do it to one truck and then its locked out until you put the stock tune back?

 

I have been told the Smarty can only adjust one speedo. I thought it could do multiple, but was informed otherwise
