[Biturbos4] 2.7T or V8?

[*~~Ebony's Husband~~* Broussard]

Hello All!
I've been on this list for quite a while now (since back when it was at 
"coimbra") and am working on my 6th Audi.  I know this is mainly an S4 forum 
but I really need a little help though.  I'm vacillating between an A6 2.7T 
6sp and an A6 4.2 (Tip of course).

1.  Any recommendations, based on anything?

2.  I'm used to the old 5000/200TQ with the "bulletproof" turbos, so I'm 
REALLY concerned about the K03 turbo failures so many on this list seem to 
have in the S4.  Is that a concern in the A6?  And if so, when were 
improvements made if any?

I plan to chip it after the warranty runs out.

3.  Is there a huge difference in performance between a 2.7T 6sp and a 2.7T 
Tip?

I've driven both and though the 2.7T (which was a Tip) is more affordable, 
the 4.2 just does what it does so effortlessly!  (And it sounds wonderful!)  
Thanks in advance!!!
