Thanxs for the fast replies, but I am kinda confused about DIYAUTOTUNE are there kits already modded to work with the 420a or do I have to do that my self?

I just want to not be having to mod de ms for it to work, and just want the std things I will want to have the launch control option too. And in the near future the boost control feature. Regarding that, how does that controll the boost? with speed, or how? thanxs!
