Looking at installing a shift kit on my 9er and I have a few questions. First off, do I need any performance mods to make this effective? (tuner, exhaust, intake, etc.) Which kits gave you guys used? I've been looking on Summit and Jegs, but all they have it under is Dodge, so I want to be 110% sure that the kits are the same. Finally, are these kits even worth it? Or are they like the piggyback chips that people blow $200 on and the computer learns its way around? Just wanna cover all my bases haha
Input is appreciated!
