Has anyone had good results from installing a performance ignition coil on a 3.8?

You won't gain anything from this whatever. It's all just a myth unfortunately.

Back in the day on some of the old carbureted V8s, you would have gained something by going with a nice ignition system. That isn't the case anymore on most modern engines.

So as much as I'd love to tell you you'd see some gains, you stand to gain nothing at all, other than an emptier wallet.
 
A Pedal Commander will make the JK feel like it has more power, gives the gas pedal the feel of the older linkage driven pedal.

A viper TB and Hypertech Premium fuel and Viper TB tunes will wake it up.
