Actually, BOVs are almost always post-MAF on stock turbo cars, but the metering issue is remedied by the return air line that runs from BOV back to the intake. Since most aftermarket kits use VTA BOVs, you see a lot of backfires during shifting since the metered air gets blown off during the shift, which makes for a temporary rich condition, and thus the backfire. This has nothing to do with your tune.
