Something else to look at......what goes in must come out. Slide under your truck and look at that stock muffler, BIG purple and blue hot spot in middle? I know dual express trucks have way to much back pressure, get rid of that stock muffler you'll be amazed how much better it runs we changed both our trucks gained a little over three MPG even service MGR in local dealership swapped his after driving this. Engine is basically a air pump, intake is the funnel putting more in won't help if it can't get out the back.
