VERY gassy baby

My poor baby has insane gas. I hear it all the time and he lets out some very impressive grown man toots. He grunts all the time because of it and he's uncomfortable. I've tried changing his formula, using mylicon drops, little tummy drops, and gripe water - all of which do not help. Anyone have anything else they have used to help? My pediatrician hasn't been much of a help.
