Y Axis Moving slower then Other axis

When I test my axis Z and X they move good but when I test my Y it moves slower then the others. I try to give it a little more power with the screw on the wiring but nothing is working.

Care to share a video?
You can also post GRBL parameter $101, $111 and $121 in case its in the setup values.

$101=40.000
$111=0.000
$121=500.000

I changed mine $111=0.000 to $111=8000.000
