Dave,

That's interesting.  I have the opposite experience with my stock S4.  It
BARELY performs better at sea level, based on seat of the pants.  Absolute
manifold pressure is only about 0.5 psi greater at sea level than in Denver.
I get 20psig in Denver and 18psig at sea level.

I can validate the loss in oomph at altitude, as I recently had my CO car
down to sea level.  I also took the G-Tech along for the ride.  HP increases
at
sea level were in the 15% range, and the 1/4 mile time dropped by .6
seconds.
I wouldn't necessarily qualify G-Tech readings as empirical, but a change
that
significant does (at least in my mind) indicate a significant loss due to
altitude.  The other very notable change was in turbo response.  My car has
a RS2
turbo and EM, and here in CO seems to "come on" at about 3200rpm.  At sea
level it was producing a hit at about 2300rpm.
Just some general comments....
Dave in CO
