i have a 2007 Dakota v6 3.7 4door 4x4, I love my truck but it has no power. any advise to help it out would be greatly appreciated.

 

Cold air intake, exhaust. I don't think they make headers for the v6, but do a search and you may find some info on the tuner stuff that people have been working on.
Gears..., like 4.10 if you want to spend the money, but you have 4x4, so you're probably like me and not ready to drop the big bucks on that even though it's probably the best thing to do.

 

You shoulda had a V8...lol

I think hypertech makes a tuner for the 3.7. Adds like 25 hp.
