Well i stuck on a K&N filter, Jet Tbody spacer, Jet performance chip and a Gibson side exit exhaust. I have noticed a decent power increase, really improved throttle response and my im figure'n out my milage this week. So ill let you know how that goes. Maybe you should give those a try.

I have the Gibson Extreme Dual on mine, also have the Poweraid TB spacer and an AirDoc CAI with an Airaid Cone Filter and I had it dyno tuned. Made a big difference! I think the 3.7L has plenty for what it is, especially if you add a few things to it:

Here's a pic of the exhaust as it comes from Gibson:


I didn't like it due to clearence issues so I modified it:
