I own a 2007 Chevy 2500 HD. Love the truck and plenty of power already, but would like a little more when I tow. I would also like to try to get a little better mileage. I already have dual exhaust on the truck but would like to do more. I am not much of a mechanic at all. So any ideas would be greatly appriciated.

 

do a search for a post called ultimate free hp mods, theres some good free ones in there. could look into a tune for towing.

 

I would do a throttle body spacer and intake or K&N filter to start. This will give you more mpg and more pulling power. Otherwise just do some searching on the web for mods that will give you the results you are looking for.

 

Tri-y headers will give you more torque, and that's what you need for towing.
