From the manufacturer

The Tremendous Pearl adds more length and more flip compared to the original Tremendous. The Tremendous Pearl features a new resin formulation, we call “Ai30”. “Ai” stands for Additive Index, “30” is the level of additive we used. The Tremendous Pearl gives you all the features of the Tremendous (using the original Guru core) just further down the lane and quicker off the spot.
