The best I could consistently hit was in the 11-13 pounds boost range. Unless it was downhill. I was 15-1600 rpm, 60-62 mph, light load on a stepdeck. Barely stepping on the fun pedal with one toe.

sounds to me like you might be also fighting some excessive drag somewhere. Maybe wind, maybe aero drag on the trailer or load, rolling resistance,.. who knows.
