why isn't my engine as smooth as it used to be?

Over the last few weeks when first starting my Jap STI, the engine doesn't run smoothly below 3500 revs for the first 15mins. After this period it's fine. I would appreciate any ideas.

I'm using super unleaded but have to admit that i've put in normal unleaded a couple of times when unable to find super. Also it was serviced in March. What does blipping the throttle on startup do? I'm not aware that i do this.
