Chiptuning Panda Multijet DPF 75 HP

Hello, I just ordered a new Panda, it would interest me, who drives one already with chip tuning, as the experiences are etc. Another thing: Does anyone know if the Punto 6-speed transmission fits in there, the engine there is probably the same with much more torque, which the transmission is also designed for… the conversion would be appealing, especially since the consumption still went down. Since when does the Diesel Punto already exist, is there such transmission on the used parts market? Unfortunately as far as Fiat is concerned, we know test-going newcomer…Thank you for your tips. Greetings Udo
