I know the Mustang dynos yield lower HP readings than the Dynojets, but what about using a Mustang dyno for before and after testing?

If a mod is worth say 25hp on a Dynojet dyno, would testing that same mod in before and after fashion on a Mustang dyno yields less of a differential than I'd seen on the Dynojet?


Or would I still see a 25hp difference ?
