The real Citation doesn't have an autothrottle. This doesn't stop you adding
one in FS though.. <g>

There are many ways to write XML gauges for aircraft and no specific code
can be regarded as definitive. It is therefore possible to write code that
produces the required effect but may not be recognised by other FS add-ons -
including the GF units. PMDG are the worst offenders here having manipulated
their gauge code in such a way that it renders the GF units totally useless.
There are other offenders to.

I've come across autobrake code which is non standard before so it may be
likely that PF have created their own autobrake facility which uses
undocumented calls in FS to work. I can't be sure about this without looking
at the code but if the GF unit doesn't work then it is likely. The GF units
actually obey all the documented codes provided in the FS2004 SDK so if
there is a problem it's likely to lie with the aircraft gauges rather than
the GF units.

Update re MCP and autothrottle.  It appears that the Citation (and the
default Lear) does not have an autothrottle switch.  Consequently, when
I press the appropriate button on my P8 and it lights up, it doesn't
actually activate anything.  Therefore perhaps it's logical that it is
impossible to activate IAS/Mach hold through the GoFlight MCP .... but
it can still be activated using Ctrl+R.  What is the arrangement in the
real aircraft - do they have autothrottle?  Other FS 2002 default jet
aircraft work OK with P8 autothrottle allowing IAS/Mach hold.

Also I find that the Disengage switch on the MCP does NOT disengage
autothrottle even though this check box is selected in GF config.

A further point.  I have set one of the RP48 rotary switches to operate
autobrake.  This works OK with the default jets which are equipped with
it but unfortunately doesn't work with my F70/100.

Rather hit and miss.
