Well, not exactly.  The only additional flight instrument that you need in
order to be able to operate in IFR conditions in addition to the Sierra is a
turn coordinator, or rate gyro of some sort.  You still need to meet all the
other FAR Part 91 requirements too, such as the pitot/static check, VOR's if
you are using them for navigation, etc, etc, and GPS if you are using that
for navigation too, since you are required to use an FAA approved GPS
receiver for navigation, which the Sierra system GPS is not approved for
sole navigation, and maybe this is what you were meaning.
