I just bought this programmer along with a viper throttle body. I need help choosing the settings I need. My jk is pretty much stock except for a 2in lev. kit and a little bit larger tires. 275/65/8. I am having trouble programming some good settings. The ones I have tried have made jeep shake while its idling. It revs to almost 5k rpm when I start it and and takes forever to shift. Any idea of what settings work? Thanks

 

I don't have either of those parts, but if i were to guess, i would try removing the viper and see how it acts with the oem tb. You may have an air leak or something with the throttle body messing with the computer
