Your in the same weather I'm in, under freezing. It does take longer to warm up compared to summer or something. My car dosent seem to cool off in the summer unless I park it over night. Otherwise, everytime I start it, its at at least 2 bars already.

I'm surprised that you're surprised.
If your coolant starts off at a much colder temp, it takes BTUs to just get it back up to its resting temp when it's warmer outside. It takes time to produce those BTUs.
Also, when it's colder outside, fuel doesn't spray and atomize quite as efficiently, nor is it as efficient for air to mix with it. (I'm talking about a cold start here.)

in the morning I've had this hesitation, but what concerns me the most is when am stuck in traffic for a little bit, the car seems to hesitate and have the hiccups...

has anyone experienced this??? this happened before I got the SC and now it's a bit more pronounced..

What you describe is also very commonly reported. Yours is more of a "heat soak" related issue, when the intake gets heated up and the engine is drawing in very hot air from all that low speed, low airflow throught the front grill. It can be aggravated by the extra parasitic draw of the supercharger when at low rpm. It can also be aggravated by the activation of the air conditioner in the summertime. This too, in time, will correct itself assuming that there is nothing else weird about your car. The ECU will learn after a few "near death" episodes.
Mine would do it whenever the ambient temps climbed and I was in stop and go traffic or coming to a stop light. I just let is nearly die. The ECU picks up on this and eventually learned to pick up the idle speed whenever the rpm got near idle. If it doesn't "learn" then you may need to check something out (MAP, IAC, etc.).
