Hey I have an auto 435i coming in early Jan, car is leased. I am coming from a CLK550 so I am hoping not to miss the big v8 much. I was planning on getting jb4 off the bat, first question is how much of a break in period should I allow the car before I throw in the tune. Do you guys feel with map1 alone performance will be close to my clk? Next I also am considering a down pipe, I heard the f30 downpipes fit the f32. Was looking into VSRF, what do you guys think. Thanks for the help.
