When you are talking about the tune for the shifts, does this just take out the "dumbness" of the shift points? I installed the transgo, and it shifts much nicer when you floor it, but other a lot of times its like the tranny is just randomly picking when to shift, like when the tach is already in the sweet spot and you just push down a little more to get it going, it will drop a gear for seemingly no reason. Or when the revs are real low and you give it a nice step but don't go wot it won't downshift when it should?
Sorry, kinda off topic, was just wondering how the tune helped.
