+1 on Bryan's comment. Its insane. 26 psi gauge at 6000 ft is roughly equivalent to 23 psi gauge at sea level. I imagine that load is around 240, and if that's the case, I wouldn't be any higher than 5 deg timing. Didn't you do timing sweeps to look for diminishing returns?
And yes it was peak load/tq I'm pretty sure.

boost is more likely your duty settings or a bad actuator/solenoid and/or vacuum hosing. or the worst scenario a boost leak
