Default Start up Idle hunt and throttle lag

I have had the MS3 in and tuned for a couple weeks now, the issue is if the car has sat overnight it will fire up and hold idle fine but if the car is already warm it will drop low twice before it catches idle. Did a search and found some threads that relate but nothing sayin "this is what fixed my issue". I would like to when I have the money get an Speed Density tune but don't know where in my area I could have one done.

As for the throttle lag, my buddy noticed it the other night when we were recharging the A/C. With the MAF sensor plugged in it throttles up slower than if the MAF sensor is unplugged. Any ideas on what could cause this and how to fix it?

Thanks guys.

I did a search in Gen III and Diag & Tune and didn't find a definitive answer. If a mod wants to move this im fine with that.
