Good modifications for a 3.7??

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.

^^^^Ditto. So far I've just done appearance mods. I'll soon start some performance mods. The srt wheels were a good start...

Next step would to add a turbo, but that would run you like 5 boxes of ziti.

Oh only 5 boxes of ziti....I can afford that....

What does having the computer tuned do? and how do you go about doing it?

Re: Good modifications for a 3.7??

I've heard that in order to maximize the full power of the intake you need to really open up the pipes which means getting a new exhaust/catback system. How much truth is behind that? Will it really make a difference?

Also, can someone explain to me what a Jetchip it and what it does. Thanks.
