You mention a 60amp power feed, did you upgrade your alternator and the wiring as well? I'm still running like a 40 amp alternator, I would have some extra work to do.
The load is rated up to 60 amps, but the EPAS unit won't pull that much full time. It can spike if you hit the wheel lock or a curb and try to load up the suspension against the EPAS motor, but under normal conditions it should be well below that. I haven't finished my install so I haven't been able to accurately measure the current draw, but I intend to eventually test it under differing conditions.
