Be patient.. SyTy r&d is prolly ~5 years behind the Buick ppl. They've been at it quite a while longer than us and there are quite a few more of em to tinker/test/build diff combos.
Do what I do and just hang out here and learn from these ppl (read: steal their ideas.. ). LOTSA good info on here and ppl that have been messing with turbo 6s for years to learn from. Quite a bit of the info here is applicable to our trucks with minor changes.
I guess alcohol is some kind of big @#$@#$ secret over there everone says is great but no one answer my post, I got one email that said "all the really fast truck will be running alcohol this year" Ya know Im not trying to take someones edge I just some good tech advice
I ran the SMC kit on my Sy, worked decent, but could have used some minnor tweaking. The problem I ran into was the spray was a little too wet, see you'll need to add a 5 foot section of braided hose to make it to the TB/intercooler, I think I may have lost some pressure in the extension tube, not totally sure though.
As far as running T3-24, you might want to do some testing on your own, more boost/timing doesn't always make more power, infact if your running the stock turbo, and stock heads you'll make the most power with mild timing(T2) and 17-19 psi.
