Tone Ring Mod............Just a way to "advance" the engine timing mechanically. If you've read any of my posts/threads about my Smarty, I can't run any "timing" via the Smarty or I'll get timing rattle. The tone ring sits behind the engine dampner on the front of the crank.
Fuel Tank Vent Mod..........This was the first mod I did to my truck, and the I love the most. It's a mod to move the fuel tank vent so you can get more diesel in the tank. Dodge uses the same tank for gas and diesel trucks. Gas truck fuel tanks need an area above the liquid fuel line in a full tank for expansion and for vapors. Diesel expands and doesn't vaporize anywhere near as fast a gasoline, so it's a way to get more fuel in the tank. Before the mod, I'd fill up with about 28gallons when the "distance to empty" on the "lie-O-meter" read 0. Now I fillup with 31-32+ gallons when it hits around 0.
Fram Boost 2 Intake.......Just a "rebadged" AEM Brute Force intake system. Won the thing in an internet raffle!! I've just changed back to the OEM intake system because the rubber on the filter part of the Fram system was starting to dry rot. In 20/20 hindsight, I should've kept the OEM intake system from the start. It's good to almost 500 HP.
Does that help??
