Obviously every car and every tuner (meaning person who writes programming, not some generic flasher product) are different.
A tune is also related to what changes someone makes on a car. In fact many rewrites of programs are required on many modifications. Ex. You can't run different fuel systems, different turbos, different cams without programming.
A lot depends on a ecu's range of values whether it can compensate adequately for a given modification.
As I see, a nearly stock boxster with minor bolt ons does not benefit much from tuning.
My other porsche would not run without reprogramming.
I have built several vehicles in which the "flash" as you call it made drastic differences and I have had cars that the benefit was non existent. (My e39 m5 for example)

What you think of my background is irrelevant; do a search, here and on other sites, ask some major league engine builders; we have run them on the track and on the dyno, they don't do much. These are Porsches, not Corvettes or BMW's; they have pretty unique programming in their DME, and are fairly well tuned as delivered from the factory. End of story....................
