TRNW-2: 6L80e performance builds ?

[Jeffery Funk]

    Make sure & install the Billet planet, they are pricey but He will snap it off.  If he don't want to buy the Planet then walk away. If you don't you'll be Sorry, don't ask How I know, LOL I have my souvenir sitting on my counter to remind me.

I installed the TransGo HD kit in one about two years ago and it definitely
improved the shift quality. It would chirp the tires at full throttle!
I have the HP tuner but have been hesitant to try it.

  We have an insurance inspector inquiring about his own personal truck,  which has a 5.3 with twin turbos !  I've not done any "peformance" builds on 6L's as of yet, haven't had anyone ask really,    I know there is a heavy duty 4-5-6 hub and shaft, but I thought someone might have come up with some stronger 3/5/r or 1/2/3/4 hub/shafts by now ?  but I've not seen any in a quick search,    transgo has their tow n pro kit
   Anyone done any performance stuff on 6L's ?  what did you use ?
