You still don't get it. If you disable the MDS system by software, the system will work, but its not optimal. The Wild Guy was trying to give you 5 minutes of good advise as to doing it correctly is to tune and properly delete by putting in the appropriate parts (cam and matching lifters) to go with the tune. It will run with just the tune, but it won't be optimal/matching. That is what this forum is for. I have learned from the Wild Guy and others. Some, like you, have so much c*r*a*p between the ears, you just don't get it.
