I just purchased a 97 Park Ave. Ultra and I'm looking for some suggestions to boost HP. I'm under the impression that it should be running about 240HP. I'm looking for at least 10-20% increase. Any suggestions?

I do have the smaller pulley (3.4") and am flowing more air that GM intended the engine to see. I hope to see that this mist i add will just balance the air/fuel ratio back to the preffered range, for i do see very noticeable knock right now.
