Even though your battery died you won't have to redo your tunes.

For a 37" tire you should use 2951mm as your circumference. That is for 37" exactly. If you have a more exact measurement of your tire diameter I can get you a more accurate circumference.

 

Oh okay, yeah i haven’t messed with it yet but as far as another tweaks with the program codes i should be fine? just wondering since we have a difference in tire size didn’t know if i had to go up or down on some settings compared to yours...

 

You may want to play with TC lock points since with your tires will have a taller final gear ratio than me. So that might change how soon you want your TC to lock up.

 

Hear ya man. I wish I had 37's, but my tranny already has 140k miles on it. I want it to last until 200k!

 

I have a 33" tire as well.

Sorry Cmandes13 I know it's been a while since you posted that but I didn't seem to get a notification.

As for you two having 37s I would suggest leaving your TC lock points at 0 until you can re-gear to bring you back to a more stock final drive ratio.

 

and if i went from 4th gear -6 to maybe +2 or +4 would this keep me in 4th for a little longer?
