From everything I have read (although it has been mainly naturally aspirated stuff), give it a hard time. There was an article in Street Machine a while back on the top engine builders and they all run their engines in hard. The idea is that you need the higher revs and harder acceleration to push the rings against the bores to make sure that they bed properly before the hone marks have worn out of the bores. If you run at constant low revs and go too soft on the engine you can get glazed bores and the rings won't seal properly.

Having said all that, probably easiest to ask the engine builder what he recommends
