So in theory the HP/TQ for what you are asking would be the same, however accomplished with much less hassle and extremely clean. Again as he mentioned, if the the car was previously tuned using a dummy MAF &/or 2nd MAF w/SAFC the tune would have accounted for inaccuracies of the setup, and therefore AFR could possibly be altered after switching to his product.
