I'm not familiar with this brand (Kramer), but all i do know is that cheap-mid range guitar that come with a floyd rose (is it a real floyd rose or a copy?) will always give you tuning problem due to their mechanic (bridge/tuning keys/neck rod)
This is true for most of all the brand in this price range.
Keeping this in mind, you could try what Axis told you, but you might want to upgrade that guitar if you really want to make a good use of a Floyd Rose.
If you are on a budget and still want to have fun with that type of sound effect (tremolo-ish), you could try a whammy pedal. It's different, but still do the job.
