3.7 Performance upgrades

Why does no one make any performance upgrades for the 3.7? there has to be hundreds or thousands of these on the road.

They do make a few. A big seller I've seen was the HEMI upgrade. It's a bolt on part

Go buy a bunch of stickers and slap them on. Didn't you know you can gain 5hp for every sticker you have!?! That is the best bang for your buck!!!

All joking aside, I think Jet makes a chip for the V6.

Fastman throttle bodies. cold air intake and cat back should help a bit.

I popped a K&N FIPK in my 3.7. Dan named all the stuff I could think of. I didn't even know of such a chip till I read this. Also threw a 40 series Flowmaster muffler on.

Regular tune up plus what Dan said. Oh, and put her in drag mode. that seems to give you the most gain per dollar.

I love how the drag mode is the most well liked and well known of all mods!

I think the liberty 3.7 is different than your 3.7 but I could be wrong..
