LOL! So you're 3 tenths of a second better than stock? Start your stop watch when the tach jumps. Not the time on the video. Do I have to teach you everything? You need to listen to yourself on how silly you sound. You have a cold air intake (guessing, because you weren't puffing your internet chest)stock throttle body and stock exhaust with a tune. You can only force so much exhaust out of the stock system. You don't understand the general function of an engine yet you want to give advice?
