M3/M4 cars have exactly same models of DCT and up to 18 PSI boost level. I guess their DME and/or transmission computers are adjusted for the power/torque surge on downshifting.
If you need a test car - I am all yours. I can remove my JB4, send it to you for reprogramming and test the results on my car . My Z will sleep in a garage till May 2018 anyway.
