So I just bought a Cinelli Alter stem (1" threadless, 26mm). So I slap it on my Bianchi Pista.. tighten up the top screw, then the sides. Put the wheel in between my legs and try to move the bars around. With a little bit of muscle, I'm able to move the bars from side-to-side. Not good.
I take the stem off, clean everything off with alcohol. Put it back on, tighten the top, then the sides again until my hand turns red and I can still move the bars. What could be the problem? Do I need some sort of shim or grip tape?

What type of bars are you using?
There is a possibility that your bar clamp area isn't 26mm. In that case, you might need to shim it.

Nitto RB-021 Pursuit Bar with a 26.0mm clamp diameter. However, its not loose from the stem to the bars.. its loose where the stem attaches to the steerer tube.

It shouldn't be rock hard where if you put muscle its not gonna give. That's asking to get destroyed duing an accident.
I got bounced into a parked car by the car beside me. Bars hit a side mirror and if my bars hadn't had some sort of give I think my crash woulda been much worse as well as my bike.

Is it, in a stand when you put it "on" ... or on the ground ?

The stem stack height might be so different that you have to throw a spacer on, probably under the stem.
