Ok, so I have the puny little 3.7 baby engine. I just installed the Powerwire from Airram.com last week, and now I'm addicted to speed. I wish that I had the hemi or atleast a 4.7, but I don't and I'm stuck with this 3.7 so I want to try to maximize the power in my rig. I honestly do not know a whole lot about engines so I would like to hear everyone's input on the best performance modifications I could do. I'm not looking to spend thousands of dollars though, so keep it thrifty. CAI? Exhaust? Spark plugs? Jetchip? which ones? etc. Thanks.
