This is an impressive tune:
http://www.burgertuning.com/N55_Stage2_Jb4.html with on the fly map selections. Wow! Didnt know BMW's were this modifiable and specially on the fly.
Im really curious to know if burger tuning will release a JB4 for the f30 anytime soon? an additional 60HP to the wheels (80 to the engine) is just whoa! And this is on a completely stock 335.
What do ppl think?
