hey guys hitting a wall here trying to lift the rev limit on 2 bf btr na skid cars and every conceivable scalar to do with rpm i have lifted to 7500, rpm is still limited to 6000 so im guessing it has to do with the tables but i cant get the 2d tables to lift so i can tune the extra 1500 rpm. probably something simple but im working to limited time and help would be appreciated thanks
