Nothing, I would assume that the only people tuning their transmission have upgraded turbos. If you're just doing downpipe, then you don't need a transmission tune.

Mine tcu is tune by ptg. Shifts are definitely faster and feel more aggressive. As for allowing more torque, I can feel but its nothing significant. This is only if you have a tune plus dp & or upgraded turbos. Otherwise its a waste of money
