So my car has nice low end terrible mid and once i hit about 80 it seems to start firing again big time. Tonight me and a lexus rx 350 decided to give it a go, off the bat hes taking me i get to 3rd gear and its just slow as hell and not gaining speed fast enough, i hit 4th or w.e it was and i started ripping ass again and beat em by about 2 car legnths i caught em with just enough time. But why is 3rd gear so slow? What can i do t make it faster? Its an AOD BTW
