I'll clarify my other post my point was that engines can use the same tune if there is room for adjustment in the tune somewhat like the OEM tune. That's how some existing flash tuners work, granted I know that some have custom tunes made before you get the tuning device but there are flash tuners that use what you were calling "canned tunes". Even though you don't get the maximum effect out of those devices there are some gains.
