Yes. This has been measured a couple of times. Basically it is a measurement of how rigidly the hand can hold the stick. Compared to how hard the tip is, the hand is very soft and springy. The bottom line is that by holding the stick very, very tightly, you might increase the effective mass of the stick by something like 1% which will get less than 1% increase in ball velocity.

So yes, a very tight grip (and the same stick speed) will move the cue ball very slightly faster. A very tight grip has disadvantages mentioned above.

Beyond that, I think working hard for a small increase in break speed is the wrong thing to work on. Study Corey Deuel.
