I am so happy that I got the spartan
tunes and the delete pipe. Guys, Unless you are really serious about keepung the truck factory, if you DRIVE your truck you will see a tremendous improvement in mileage.
I am averaging 13.4 mpg around town in winter and in the summer I can get 20-21 freeway empty and I seriously got 14.0mpg towing my 10,000lbs trailer on a 1000mi round trip.
Before, the best mileage that I got was 15.2mpg on the freeway empty.
I put the package on at 6400mi and didn't look back. I did keep the factory exhaust and in one piece just in case....but I highly doubt the nessity for it.
