I must have did something wrong, when I plugged the tuner back into the truck it made me select a new tune and wouldn't let me modify the tune I already had. And the ratio hasn't changed

I figured it out. I was trying to paste it in the tune folder, but once I just clicked the file and drug it to the intune it imported it and it worked just fine. Speedo is fixed and no more abs light! Thanks!
