As said already, those times and speeds look just about right to me.
The most important thing is practice and getting everything just right.
My car as it is now was running 14.5-14.7 most times out. Then last time everything just 'clicked' and I ended up with a best of 14.2. With exactly the same car.
I *can* get a 2.1 60 foot on my normal street tyres. It can also be up to around 2.3/2.4 as well.
Keep practicing and you will get faster.
