A/C turned off Engine Overheating

Ok sigh... I can't turn on the A/C without overheating the engine. Another problem Im running into is that engine fan keeps running when I turn my car off. I just got a dyno tune last week. Are there any adjustment I can do on my own on the canned tune without have to taking it back to the shop? And what should my settings be for a Diablo tune for the engine fan?

What are your coolant levels?

What's the coolant temp when you start the car, and then what is it after 5 minutes of idling (with no A/C)?

Who did your tune?

I have no idea. Im new to this whole tune thing. I had S&S perfomance do the tune. After 5 minutes of idling the arrow slowly moves to Hot. I don't know the coolant temp and all that. Sometime when Im driving the temp moves back and forth when i have the air on.

Press the button on the arm that controls your turn signals. That'll take you to the vehicle information center. Turn the knob/wheel until you see "coolant temp." What number does it read?

Did you install a thermostat? If the coolant system isn't correctly burped, the engine overheats....
