John you are correct the Bullydog product is just a fluidampner. You want see any peformance affects, but your engine will be extrenally balanced much better, which in turn is much better on bearings. It's more of a longevity item. They do make a huge difference over stock.
Most of the vendors here have them at a very good price. I would also check with ITP diesel. I think Dennis has a great price on them.
