I don't have a lot of exposure to the more recent bottom brackets, but I would generally never describe a bottom bracket noise as a "click." It's usually a lower frequency, more like a "clunk." You've eliminated pedals, so it's crank on spindle or perhaps chainwheel rivets. You might try removing the crank arms, making sure the mating surfaces are clean and smooth (try steel wool) and then reassembling to proper torque.
