I have done many before/after tests. Using a MAP/TPS approach instead of MAF to ditch the AFM.

Way, way more noticeable than chips, filters, exhausts, etc. More extreme low end than a 2.5. Yes that is correct. All revs and throttle openings benefit. Again, much more low end. Very crisp and responsive compared to stock. Heck stock can't even take lots of throttle from idle in neutral - try it it will choke up cuz it goes lean.

There are no drop in and drive away conversions. So far all approaches need some tuning time, preferably on a dyno. I was able to street tune using data acquisition and running the car in parallel AFM and MAP/TPS..
