Short version is our ECU's have very complex timing maps that are constant changing things based on many different variables, some of which really don't matter for a performance only tune. Uprev does NOT have the ability to guarantee the timing settings you put in actually are used as entered.
ECUtek simplifies the timing maps so that all these "other" variables can't affect timing and you actually get what you enter instead of the ecu doing whatever it wants.
If the ECUtek was around when I had my car tuned I would have used it instead of Uprev.
