I currently own a 2007 f150 with a 5.4l. it has a aem brute force intake, bbk 80mm throttle body, diablosport predator tune. i currently have 3.31 rear gear and looking to upgrade to a lsd. my dilemma is that i cant decide whether to get 3.73's or 4.10's since itll be at the track and on the street. Any suggestions?
