As you can see I have a similiar setup as you do(read sig) My spark plug gaps are at 35 and my plugs are 2 heat ranges cooler. My car seems to pull hard up to 6200rpm, so I would think that the gap change should be your first step. My car runs very rich for some reason we made 8 dyno pulls in a 4hr span and finally got the air/fuel ratio to actually show up on the graph by removing the fmu. I think I need to have a custom chip made.
