Running stock Busa except for airbox and header only. Installed Powercommander and a Air Fuel Ratio meter. Spark plugs are stock. The plugs are carboned up after a couple of runs which tells me i am to rich but the air fuel tells me i am running lean Is there some one around Houston that can help me tune . Any one have some ideas thanks Spivey Racing
