Yea, it was well worth the money. The power I got out of it was crazy for less then 10 mins of my time
plus I have bigger tires so I was able to adjust the speedo. With stock tires I could burn them off and too top it off the cortex has a warrteny with it a good plus in my book
The K&N and the Flowmaster helped a lot with the mpg's. When I first got the truck it was getting 12-13 mpg city and now I'm getting 15-16 city with 93 oct. I did drove for Detroit to San Antonio 4 times and at one point I hit 22 mpg on a tank.
So yea very happy with the whole set up and it works great. Defiantly will buy one for any other trucks I have.
