get headers, remove mid muffler, get better spark plugs and cables then u do remaping!
3.68 is better 200/205km/h max speed but it will go to 60mph in 9sec
I will get LSD just for drift (not for better pefrormans)
bhp is not important as u think!
exp. 323i is faster then 325i although has 20bhp less!
