Since Uncle Sam saw fit to give me back some of my hard-earned money, I've done a couple of things to my truck starting with the DIY Intake. That gave me about .75-1.5 mpg increase, very nice.
Fixed the door lights too.
But the BEST thing I did was get rid of that stupid cup thrower and buy a holder!
The color doesn't match exactly, but man is it nice to have a place to set my coffee now! Got it from Powerstrokeshop.com, about $45.00 cheaper than what the dealership wanted for the same thing. Even better!
