I don't think I know the full answer to this, but I have seen other forum members run an OTS map as a placeholder waiting for a custom tune. I think you should be okay because MHD tunes based on target engine load, not target boost, so it'll just be an unoptimized tune (missing out on 6k to redline), but you should let more experienced members chime in.
