Noar, welcome first off.
Now, in order to get help you need to make sure you post in the right location. This would fall under either general discussion or problem, dealer, etc...
Ok, with that said, your car will react differently with boost depending on the weather. The PCM will increase boost in warmer weather and decrease boost in colder weather. you can take that control away from the car by running a new boost line from your turbo directly to your wastegate but I would recommend getting either a boost controller or a aftermarket wastegate (kinetic and AGP are both pretty good).
As for the temp, it is normal. if you want it to run cooler you can swap out the thermostat for a 180 degree one from Napa (part number THM 153) and it will keep your car running inbetween the hash mark between 140 and 200 and the 200 mark. I think mine sits somewhere around 175-180 most of the time. It is great if you are into racing since it helps you keep the engine cool.
PM me if you have any other questions.
