Thanks for the reply . And yes I am not thinking about putting down pipe or catless dp.
Ya probably the JB4 might not be ideal if I can only use map 1. I think the result
Is similar to JB plus ?
Is MHD and BM3 mod consider ECU tune?
I guess I would try the JB plus along with sprint booster. Sprintbooster
Is fun and addictive. Once you have sport mode enabled you don't wanna change it.

Hell even new meth systems come with their own dedicated controller anyways.
Oh, JB4 doesn't remove throttle lag for 2011 cars or at least in my experience with it as I have 2011 535i xdrive but not a JB4 anymore.
