Typical stock N/a coyote I wouldn't go past 7k, but with the boss combo and the right valvetrain people rev it up to 8500.
Mine is all stock valve train so I don't go past 7k. When N/a I shifted 6800 or so. Boosted...well I haven't really tried being that consistent with my shifts and you can tell I vary from 6k to almost 7 on some.
