So my friend recently purchased a 2009 135i which comes with the N54 motor (Twinturbo) so far he had installed the BMS dual cone intakes and JB4 he didn't run me on any of the performance maps he set it to map 4 which is a Performance OEM map so I'm guessing pretty much stock? Below are the vids of the 2 runs. Both were 40 rolls and went up to about 110. Mods are in sig
