430/500 hp REL 32.6

DDDL says the 500hp setting is active, yet the engine pulls harder on cruise. Is this file a 430 on the pedal and 500 on cruise only, or is there a way to set in to a straight 500 file using DDCT?

Or do the timing/fuel table differ for cruise setting no matter what?

Is there a straight 500hp file with only one hp rating?

Thanks
