I see Steveo replied. I do not have much to add to what he said. My car has a stand alone TCI controller, and I am telling you is was night and day difference once Steve "adjusted" things. Mine does not hang up on shifts. Of course for the real fun stuff I use the paddle shifter. It is just bam,bam bam and you are gone. The shifting then is instant. I have a pos floor shifter, so I never use it for playing. I am telling you, think about the stand alone deal, you tune the tranny for you and your car, not some preset deal from a out of state tuner.
