Got a professional tune but not sure if everything is working correctly? If so then an AFR gauge is the tool that you need to monitor your engine in real time. These AFR gauges will display if you're running too lean (13:1) or too rich (10:1) under peak boost conditions. Avoid the risk of detonating your engine due to improper fuelling conditions.
