PS2 Tray Ejects/Closes Too Fast!!!

[cobraxt]

I have a Neo 2.2 Pro installed in my V1 USA PS2.
When I press the eject button to swap a ps2 backup, the cd tray comes blazing out real fast and sometimes shoots the CD out too. And when I close the tray, it goes back in real fast also, fast enough to damage the PS2.

What is wrong? Please help.

Thanks
