Default A/C not working - help needed

I did some mod to the car, including a FAST Intake and a LS2 t/b.
When I turn the air cond. on the light blinks until you keep the rpm's
up. When the throttle position drops below 12% the computer shuts off the a/c. I checked the coolant with gauges and everything seems ok. Is there a something in the computer ( a setting) that I am missing .When the rpm's are up, a/c is cold and the engine idles smooth. As soon as you let off the gas and it goes to idle the a/c constantly goes off and on. The idle is set at 975.
Any suggestions and help will be appreciated...:cheers

did you remember to reconnect the vacuum line under the intake next to the oil pressure sending unit?
