i have a hyroad drilled pin below bridge cg right of center span about 1 1/2 inches, didn't change drilling, only the span to fit me. right hander owned before I.
i'm left handed so the CG is negative.
how should it react on the perfect conditions for the ball with this drilling?

The cg being right should give it more length. The ball should have had a weight hole unless the top weight was next to nothing.

For a right hander it would give you length through the heads and depending on the weight hole location should have a strong angle to the pocket on the backends.

If no weight hole was required then you should still get plenty of length and depending on your style of bowling and the aggressiveness of the ball a moderate to decent backend reaction.

Weight holes to balance the movement of the cg and its weight will have the biggest effect on the balls reaction.
