Well as you can see in my sig i should have a very loud car. Ive recently tuned my fuel tables to lean it out a bit and decided it was too lean so i made it a bit more rich. Suddenly the car is alot quiter, idle seems to have dropped to normal(has been idling 1 or 2 hundred rpms higer than normal) , and it seems alot smoother. I havent lost any power or anything. What gives? does leaner = louder?
