I. Have 08. Unlimited. With 1.75 in daystar lift. Running 305 60 17 BFG mt. Which is somewhere around a 33. My question is. Does anybody have any suggestions on setting up my vivid prgmr to be able to. Set cruise on the interstate. At 70 75 mph. And. Not get all the up and downshifting. It. Even does it on the highway cruising. I really don't like turning OD off but if that's all I can get I will take it. Damn weak. 3.8l

 

What gears are you running? The first thing you need to do if you havent done so is calibrate the speedometer by entering your tire size

 

I am running stock. Gears. Not sure on ratio. But I have calibrated the spoodo also

 

I would guess you have 3.73 gears. Without a re-gear, you are going to have that problem. Overdrive off is the best way to help with the gear hunting. You might want to try out the advanced transmission tuning option. It will definitely help

 

so what brand gears and ratio would you recomend???

 

I have 33's with a procal running 3.73 gears and I run od at 75mph+ so I'm guessing u must not have 3.73

 

So how do I go about finding out what gears I have?

 

Not sure exactly where but there is a site where u can enter your vin and it'll give u your build sheet

 

I have. 3:73's in it
