Jeep JKU performance upgrades

So I just installed a coolant air intake but I don't see much of a change but some noise when I kick it. I have a 2010 JKU rubicon 3.8L and I want to get the best performance upgrades. Any suggestions?

The only performance upgrade that works on the 3.8L is a Supercharger. A programmer will help with drivability issues like throttle response.

while both can have the super charger, the 3.8 can have headers as well as the throttle body from a 2008 dodge viper whereas the 3.6 can only have a cat back added.
