i just got my programmer and wanna know if anyone knows some good settings for 37s

shifting timing idle firmness ect.

for extreme mode and towing

 

I have the edge and 35's and my only suggestion is to double check your spedo with gps because I did the calculations an I was still off quite a bit. I kept going down in tire size till my gps,cell phone gps,and spedo all matched. Also as far as other changes I leave mine in level 2 raised shift points to Max and increased firmness quite a bit also increased timing one degree. Don't make huge changes though start gradually and see how the truck performs first
