hehehe...u talking about FI cams or what? if u're currently std cams, upgrading to M3 3.2 cams is a good option, if ur engine is M50 vanos. Non vanos engines u need to get aftermarket cams then. not cheap. and wont be much power if ur FI setup is not for high power

ramsing, do you activate or deactivate the vanos unit when you run boost?

the vanos helps in spooling the turbo. my vanos is active when full boost hits.

what is the difference between the cams of M50, M50TU, M52 and S52 and M5x(FI)?
