That question is really not answerable. Different engines respond in different ways to certain mods. If the tune you have in there now is correct for your combination, then you will not benefit at all with a different tune. If your tune is not what your combo needs then you should see decent gains with a proper tune. The tuning software is not what makes power. The power is in the tune info. It is not the wand, it is the magic that you do with it.
