I had the fass system too. After losing multiple lift and injection pumps under warranty. It certainly helped but it eventually failed and when it did I lost vp-44's.
My truck had the dreaded death wobble too. A kit from solid steel industries that braced up the from end and a special set of alignment specs cured it. And my truck went through from end parts like candy too. Tried Moog replacement parts with little more longwtivity noted.
