I have always run my cars with zero fuel on the overrun until the revs drop to around 1,500rpm when the idle fueling kicks in.

What do you do? I am wondering if with a turbo if I keep it fuelled on zero throttle if the little puffs will keep the turbo spooling a little longer or if that it will just waste money?

You'll get some crackle and pop but nothing to keep the turbo spinning without air to help combustion. The proper rally style anti lag relies on a lot of air getting in either through a throttle that doesn't close all the way or a big air bypass valve to do the same thing (and heavily retarded timing I'm told).
