Dont want to get in the middle of another DV vs. BOV discussion BUT to be fair can we please NOT post false info that could scare people away from being able to make a researched decision with mis-information on topics that may not be fully understood.

Simply because DV's came on the car does NOT mean a BOV is not designed to and will not efficiently release excess boost pressure under higher than stock psi level conditions on the N54 application. The "other" applications you may have heard of running into "lean" conditions most likely had the MAF (Mass Air Flow) sensor (Suburu's/ Evo's) and not the TMAP sensor that is found in the N54. A BOV will not hurt or damage anything on the 335i and there have been no tests that can suggest a DV is safer or more effective on our application than the BOV. If you feel there is, please explain your reasoning and you may want to let companies that build and tune cars (Active Autowerke etc.) that a BOV is dangerous. Lets try to post what we have actual knowledge about guys, and not what a friend's cousin's brother told happened to his 2001 Suburu WRX or something. This is "E90post".

2 year old thread back from the archives, eh? I don't see how a bov could damage the car, but I just don't think I could stand the noise they make for more than one drive around the block. That thing sounds horrible! It may be a beneficial device for boosted cars, but how do you put up with the sound every time you drive your car?
