Hello BB2405 are you currently running the jb3? I'm looking to make the mod this is my first time doing a tune and my fist BMW 535i F10. Is there any problems get CEL codes and if you don't mind could you list everything I would need. I am pretty handy working on engines, anyhow thanks
The jb3 is good because it takes about 10 minutes to install and 6 minutes to uninstall. As soon as its in you feel power gains and your pedal becomes a lot more responsive. From a dig I'll spin through first which is impressive for this heavy of a car.

All you'll need is the jb3 stage 1 and maybe a burger tuning USB in order to change what boost your running. But I'd recommend getting the jb4 stage 2, the power is supposed the be pretty impressive.
