Insight Archery?

Is there a way to add your INT instead of DEX to ranged attacks for Pathfinder? I'm building a Human Rogue/Alchemist using a double-barreled pistol.

There is a feat which permits you to, as a full-round action, make a shot that adds your INT to the damage roll. Otherwise, I don't believe so.
