If you are satisfied with the way your trans is now I believe you will be surprised at how much difference you will notice with Bill's tunes. I believe you will like the slightly firmer shifts. Just keep in mind that you will be putting more power to the trans & it seems like it pretty hit & miss, some trans last quite a while & some don't.
