Ya all may be running BOV's with your AFM engines, but think where the measurements for air volume are taken. The ECU calculates this from AFM signal. If you have a BOV fitted, you are venting some of the air, which has been used in the calculation by the ECU. When your BOV dumps this air to atmosphere, there is nothing to compensate for the loss. You will end up with a richer than required air fuel mixture.

yes true, a richer fuel mixture when vented on gear change. which also can inturn over time can wash down the bores of oil premoteing premature ring wear.
i havnt had fouled plugs since 2002 when i first did my 4agte conversion, and there is no difference with my fuel economy over the factory 4agze set-up.
