First check under Engine>Torque Management>Engine Torque> AC Torque 'Max Retard'. Zero out that whole table.

I usually goto Engine>Torque Management>Engine Torque> AC Torque Vs. AC Pressure and increase this table. This effectively adds IAC and fixes weakened idle. If you only take a hit when the compressor first engages (or to eliminate/reduce this after you fixed the weak idle) I use Engine>Torque Management>Engine Torque> AC Torque Vs. Inertia Torque. Once you up this value to fix the hit, you may get some new RPM hang or light flare. To get this gone, I increase the decay that applies to the extra airflow that we just added to cover the hit on compressor engagement. This decay table can be found next to the Inertia Tq table labeled Ramp

Having the base running airflow correct is the first thing you should worry about (if you haven't already). Once you have a good table (+/- 0.5 g/sec LTIT and STIT ) watch the LTIT gear/AC on when you turn the A/C on. If they start climbing way up the aforementioned tables in the torque management tab are not high enough.
