i was wondering if i close the spark plug gap a bit would i get better fuel burning from my supercharged 4.6? i was reading a couple different articles on supercharged stangs and i noticed that they closed up the spark plug gap some, i am still running w/stock gap. would this help with producing more power and burn cleaner. i have noticed that the car runns a bit lean, i just replaced an o2 sensor and would like to burn clean. any advice would be greatly appreciated. thanks, ron
