I have no clue where to go after changing my idle and changing the gear ratio.
I have a 2001 Chevy Silverado 2500hd 6.0 4x4 auto

Hopefully some of you guys can help me just bought an intunei3

The platinum version. And I bought it to really change the idle speed for my alternator but I want to use it to plow more effectively which I think I did with a 4.3 gear ratio. But theres gotta be more. I cant seem to download premade ones and I am fully updated. Also I thought you could see real time graph data of car..

the premade tunes are in the menu, what tune are you loading?
What is the issue you are having specifically?

did you physically install different gears in the differential??? if not, then you still have stock gears man.. do NOT change the gear ratio setting in the tune. You only change the gear ratio setting in the tune when you have actually/physically installed new gears in the truck... so if you did not actually install new gears in the truck, then you need to put the gear ratio setting back to stock in the tune.
