I personally, keep the bump and displacement separate. What do you mean by "I maxed out the bump/displacement dial for this map" - don't think there was a dial for this. Get displacement working first. Make sure displacement is switched on in your render settings. In general you will be disappointed with displacement at higher values - unless you have a massive map (4500x4500 - or whatever the max is).
