My deadlift lags a bit too, mostly due to an injury. But some big lifters have always given me the advice to always pull from different heights. Say one day full range, the next day from just below the knees, and another day at the knees. You get the idea, just mix it up.
Brooks Kubik suggests starting with a higher rack pull and lower the bar every session until you are pulling from the floor with the same weight. I've never tried it but it sounds interesting. One problem with this is you need small adjustments in your rack.
One more thing, rack pulls can bend a good bar. Better to pull from blocks, most guys feel it's more natural too.
