cold start?

Ever since I had my PFC tuned last week, I have had an issue at syart up sometimes. It seems like it going into cold start, the rpm's will flucuaste for a minute between 1500-2500 and then it levels out. It also seems to be off as far as the setting. It is set at 720 but reads 800 at idle and I am getting 14 hg @ vacuum instead of the 16hg I am used to. Does this point to a vacuum leak? I did blow a hose while testing and it is now in place and zip tied on but maybe it's another hose that came off? Can someone help?

Might want to do some reading in the PowerFC forum. I know some of the idle problems can be fixed by adjusting the idle adjustment screw under the throttle body.
