Do you have an auto or a manual? If you have a manual do you allow it to coast down in gear? If not, you should. And since you know how to tune, make sure the FCO (Fuel Cut Off or sometimes refered to as DFCO). Basically what it does is shuts the fuel off to the cylinder during "coast down" in gear. This rapidly cools the motor. Also, don't be heavy footed in traffic and make sure to blip the gas occasionally (every 45 or so seconds if you are stuck in traffic) if you have a manual, this keeps the coolant flowing.
All of these cars have an issue running AC while sitting in traffic and keeping the motor cool. I don't care if they're stock or not...the little 2.0L (I'm assuming you have a 2.0L because you talk about tuning) with the turbo have no chance at staying cool in city traffic...especially when temps outside are over 100+ degrees, let alone with the AC on. The motor just has to work too hard to turn the AC compressor.
The above works for me, but rarely does it get above 92 here in Detroit...and rarely do I drive my car when it gets that hot because when I use the AC it gets worse gas mileage then my Charger Scat.....
My advice: Put a "cooler" thermostat in the car. I think the OE is 185 degree...I'd go to 150 degree if you could find one! Or if you are only driving it in 100+ degree heat all the time, you might consider pulling the thermostat all together. I don't recommend that, but seeing as how you said summer is 110+ all the time...I don't think it would hurt too much. And I'm not certain if a much cooler thermostat is available. Maybe someone can weigh in on the pros/cons to pulling the thermostat altogether in a hot climate like this.....
