With a/c on, it never exceeds 220.
As explained above, the high speed fans are always on at speeds below 35pmh when the a/c is on, so yes, the phenomenon of the engine running cooler with the a/c on is true, simply because of the altered fan operation.

I have not put on my flame suit for awhile so here it goes. Many of us here on the forum have solved our engine temp concerns by installing a 160 degree t-stat and programming the fans to turn on at lower temps. I live in FL and need every advantage I can get when it comes to battling heat and I have had no negative side effects from this mod, just much more reasonable coolant temps.

Find a way to control your fan off / on temps, Chevy sets them way too high for pollution reasons. A cooler thermostat helps too.
I run high 180s regardless of conditions, hiway, intown, drag strip, autocross, summer, winter, etc.
A4 trans cooler also, keeps the trans temps from 140s to 180s.

Did they at least give ya a little kiss and a hug when they were through with ya? 
I see 196-198 in on freeways, etc and 205-210 in stop and go on a hot day. I have a LS1WCK water cooling kit I installed about three or four years ago.
