I've had a couple of Remedys. Old one with the 'standard' shock did bottom very easily (though sorted with volume reducers in air can).
Never felt my DRCV shock bottom out and its had a fair bit of abuse. I weigh 150lbs and I'm running 135psi rear for 30% sag. I've been struck by how well it does pedal but I'm used to heavier bikes. You checked you're compressing the shock to equalize the chambers and are getting the right sag?
Other possibilities that either the shock is f***ed or as others have said you really need a shorter travel bike.
