Mine never update past that until they have cleared customs,so all of mine have went 4-5 days at least,with no updates.
Now,i have one not from Fasttech,but another chinese supplier,that was moving really fast,from the day i ordered,it only took 4 days to get to Chicago and get processed through customs.It went through customs Sept. 28,and has never been scanned again since then.If it doesn't update by monday,i'm contacting USPS customer service and see if they can find out what's going on,i hate waiting,and i hate not knowing even more haha.
