Cat 315C L- Seems sluggish when running automatic throttle

I have a 2002 CAT 315 CL that seems sluggish when running the dial on any setting. It does progressively idle up on each dial position. If I switch the manual toggle under the right arm rest to manual it seems to come alive. Tracks faster and all around seems to have more power. The serial number prefix is CFT. Is there any calibrations that need to be done that I can do myself or is it time for the CAT Tech to come look at it?
