You have to understand that the ECU will not change like the OBDI systems did, so you can't get that kind of increase pre tune. OBDII was brought in to be stricter and make the engine try and get back to the factory state. I understand that these newer versions of OBDII are even more so this way, very hard to change the overall running.

OBDI only adapted to the situation, so an easier breathing filter, it would put in more fuel for example.

ODBII, would see the easier breathing, but try and tune it's self in order that it didn't put more fuel through than it's original design was told.

Basically, you're expecting too much, it won't happen, the tunes are needed these days more than ever because they change the mind of the ECU as to what they should be doing.
