Every pump acts different so we can't tell you exactly when your truck will runaway. In fact some trucks can have the fuel screw bottomed out and not runaway.

If you crank the screw in and the RPM hangs when you rev it up, you are on the verge of runaway and need to back the fuel screw off.

Basically, when you start messing with your fuel screw, disconnect the intake and have a board ready with a friend standing there. Turn the screw in a turn and blip the throttle. when the rpm's hang or float, back it out about a half turn. Make sure to lock the nut down or the screw will slowly turn itself in through vibration. If the truck starts to run away, clap the board over the turbo inlet and it'll kill the motor for you.
