how can you tell if your running rich or lean? i heard of checking the spark plugs, but for me they look clean but i feel like i got my fuel reg. up abit high, cuz i can feel the car bog out at wot and can smell gas from the tail pipe and blow alittle bit of smoke when i beat on it.
i'm also running the skunk2 ecu, which i was told will read rich so what would be a good setting for my fuel reg. to be at?

 

You usually can feel when your car is running rich.
Does it bog during the day? I assume it runs great at night though, right?
