Remotes on a LS.

looks like you have a bit over 9 gpm of hydraulic flow at rated rpm.
Depending on how your hydraulics are run when you are using one the other is not getting flow.
If your remotes are after your fel when using the remote on a hydraulic motor then adjusting the loader lift or curl
the flow to the remote will be restricted.

9 gpm isn't nearly enough flow to run even a small hydraulic motor.

It wouldn't be the best but they are avilible, as an example here is an auger with a 6-15 gpm rating;
