I have a 2004 Hemi Ram Quad Cab 4x4. Already have a 40 Series Flowmaster 3" pipe and a K&N Cold Air Intake. I'm not looking to race Mustangs or Civics (like some people on here) but wanted to add a little more low end grunt. I know 4.56 gears or a SC would do it, but don't feel like paying that much money. I was thinking either headers or a power programmer.

However, I've heard mixed signals about the programmers. Some say, no matter the brand, its a waste of money. Others say it works. The headers are tricky as well. Do they work? Yeah. Are there trade-offs? Sure, we've all heard horror stories of headers leaking. Thanks for the advice.
