I would either stick with the stock gears or only go up to the 4.10's at most anything higher will probably drop your 1/4 time. I would do one of the garrett turbos. Also you might look at this turbo Elite Diesel Engineering Turbo Kits for 6.6L Duramax Don't know of anybody that has one but looks kind of interesting.
