I am very pleased with my path of increased fuel mileage. Darn if it didn't work. Here is what I did and the gains that I saw. Each step was done one at a time. All MPG stated were hand calculated. I did these things in order as listed. This was a combo of Town and interstate driving. Truck has 29,400 miles on it.

Rokktech- Increased 1 MPG- Was getting 15 MPG and then got 16 MPG

PS fuel additive- No increase in MPG- Was quieter at idle. Better PSI on Fuel gauge. Was at 7 PSI idle- Increased to 8.5 PSI Idle. Test done with new fuel filter.

Quad Std. set on level 1(30 HP setting)- Increased 2 MPG- Was getting 16 MPG now get 18 MPG. I did notice some timing changes with this setting. The reason I say this is because with the Rokktech(2 Degree increase) and a cold truck I would have some clatter until the truck warmed up. When I turned the box off I wouldn't have any clatter at all.

AFE Stage 1- No increase in MPG- Decrease in EGT by 50 degrees.
