This should give you a good idea of what adding a BOV does to a car

If you have a high boost application and you tear your DV membranes frequently there is the GFB DV+ that could be considered a performance upgrade.
Generally DV are not a weak point on most cars, and are pretty cheap/easy on the M at least to replace when/if they fail. I think I replaced both of mine for $120, and under 20 minutes. Mine were fine vintage 2011/61K miles, I replaced them tracking down a 30FF error. They were not the cause. |
Thanks. I am familiar with BOV's, was curious on what difference it does in the X5M platform, which is really the same as I know them be. With a stage 1 tune, seems to me the OEM Diverter valve will do fine with the mild boost increase.
