all,

I have a 2007 Unlimited X, automatic, with 4.10 gears. I also have a Pro-comp accupro programmer that will adjust shift points to account for larger tires. I have already re-programmed to account for the stock rubicon tires which replaced the stock 29-inch tires. If I were to go with a TF BB and 35-inch tires, will I really notice better acceleration just due to re-programming?

I do not want do my gears yet cause I'm still deciding on upgradinx axles.

 

someone must be using a programmer and can tell me how changing the shift points may assist with bigger tires and how this will differ from changing differential gears.

 

Well, it will basically firm up the shifts, and hold you in gear longer. So it doesnt bog down when it shifts to the next gear.
