I have no idea wat all is done to the truck. I just bought it. Is there any way I can find out wat all is done to it that's not going to cost am arm and leg? Also has 35 12.50 17's on it. Speedo is off and no idea how to fix it

speedo cant be fixed through the tune on these trucks unfortunately...

You can go to options/show last tune written to see what is in the truck now.

Thanks
