I'm not really looking for 500 yet. Maybe someday when it is no longer the daily driver/ weekend family hauler I'll go for it. By then it will be the 600-700 club or they will come from the factory with 500 and I'll just be keeping up! One good thing has come from these up grades: The wife likes to go out and let me get under the influence more. This gives her the opportunity to drive it! Saturday night we were headed home and she says "I'm going 80 and it won't shift?" I said "Is your foot to the floor?" She replied "yes" I then tried to explain how things worked and her only reply was "I like it when it pushes me into the seat" I think I might be close to making 300hp, I can't imagine what she would do with 500! I'd have to sober up and that ain't right.
