Is there a way to create Alchemical items to be more powerful?

[Player III]

I have myself a character whom uses a fair sum of alchemical items, but as the adventure progresses and the CR increases many of the items become rather useless or situational to a point of uselessness. When you create the items, is there a way to increase the save DC's of the items? After a bit, a fort or reflex save of 14 really is not that difficult. And on that same note is it possible to increase the dice damage value?

No. They don't get better, and they were not intended to be of much use after the lower levels. You could use the alchemist class instead of the class you are using now.
