Idle Problem?

My r33 gts just got retuned and now I'm noticing that the idle will go from about 1k to 1.3k constantly no matter if you push the gas or not when the AC is turned on. Turned to floor it's not nearly as bad but still noticeable and with AC off it doesn't do anything. Apparently it has something to do with the parisitic loss because of the AC but I don't know why or how to fix it?
 
normally when you turn the ac on the idle will raise about 2-3 hundred to compensate for the parasitic loss, idk by thw way your describing it if thats whats happening though
 
was this the car at the fairgrounds this weekend? Black?
The idle problem sounds like you have a vaccum leak boost leak.
 
Yeah I was at the fairgrounds. And yeah I know the revs will go up a few hundred but this constantly revs up and down a few hundred instead of just rising and steadying off.
 
when i turn my AC on the idle drops. but then again the AC doesnt blow cold...it just blows...any one kno wut this is?

Im assuming the compressor is kicking on by the rpm drop, but is the system charged? Do you have all the components for AC? Swing that thing by SMDG's shop in Ft. Lauderdale - those guys will hook u up - or atleast point you in the right direction
