Use BPM 164 and Offset 1485 roughly. Make sure you have Beatsnap divisor set to 1/2, you shouldn't really have any notes on blue ticks. After you change the offset click up top, Timing > Resnap all notes, then go through the song and make sure the notes fall on the right beat aka 'tick'.
You're going to have to re-do a lot of note's positioning and slider lengths. When you're repositioning or mapping, make sure you have 'Distance Spacing' set to on. You can turn it on by pressing 'Y' and adjusting it by holding Alt and scrolling your mouse wheel. This makes sure notes are evenly spaced and not confusing to play.
