7890B signal output very low compared to I/O/PQ

We have a new 7890B with ALS. We're running ICS 3.0 on an enterprise Empower 3 installation. The problem is that the signal output in Empower appears to be somewhere between 1% and 10% of what it was during the I/O/PQ which was done on Chemstation. It is also low when we compare our peaks to Agilent's literature for a particular method. We have no reason to suspect the GC as it is new and delivered typical sensitivity when run on the service rep's laptop. We suspect a configuration issue with Empower. It is making it really tough to do residual solvents.
Can anyone steer us to a setting that needs correcting?

    Agilent technical support is throwing up their hands - they have nobody who knows enough about the ICF to help. It seems likely to me that it is a translation error either between the hardware and the ICF or between the ICF and the rest of Empower. Perhaps Empower is thinking millivolt-seconds when it should be thinking picovolt-seconds (or whatever unit would result in a 5 decimal place difference).
