The reason I disconnected it is because the guy that tuned it at the machine shop said not to run it. I trusted his judgement, but I will hook it back up and see if it changes anything.

Well, I don't know why he advised this. The GM engineers (and EVERY other manufacturer) thought it was necessary. It gives you MUCH better MPG fuel economy in a cruise situation (freeway) and any other part-throttle driving situation and with a BB, unless you own a gas station, this is important! As you know, it does not effect idle or full throttle timing, just light throttle opening. It will lower the heat generated during light throttle. I would definately make sure it is functional and hooked up.

With a stock fan and the AC condenser and the other cooler all in line for the air flow, maybe you will idle a little warm but after you hit road speeds I think you should be OK. Is that condenser in good condition without a lot of bent fins?
