You don't want to tighten the limb bolts tight so they bottom out the limbs. They should always be backed off at least a half a turn. In your case, that would be 1/2 turn for the top limb and 2 turns for the bottom limb.
BTW, the tiller isn't "off" with the limb bolts tightened. The most common set up for a bow is about 1/4-inch positive tiller. Folks have to standardize somewhere and Dryad apparently went with the conventional standard for tiller. Of course, the advantage of an ILF bow is you can change it.
