My current mods are in sig...including the reflash but I added the licp after the reflash and I've been worried about running lean....I don't have a wideban yet and my exhaust looks a little white....I'm running 91 octaine gas.....so I ran evoscan and my highest knock sum count was 3.....jestr told me below 4 is good....but just becuase my knock is ok does this mean I'm not running lean? I don't know a whole bunch about tuning so whatever you guys can input I would appreciate it, thanks!
