Sure there is... You don't see the benefit of making sure your hitting the right amount of boost your supposed to be hitting at any given time? I know modern electronics adjust boost according to outside factors, but it is NOT as significant as you all seem to think. Any problem that can create a boost leak will alter the boost reading more so than environmental factors any day of the year, in any conditions.
Its as pertinent a gauge in any forced induced car as your gas gauge is. AFR/Boost/EGT/Oil press/Oil temp are all pertinent in a boosted car, even more so if you track and are planning on modding anything to raise the boost levels.
