It shouldn't because the Only time bovs are open is when you off the throttle. This is how my turbo talin is setup from the factory..time to get in the lab..and make something up

That's a well-documented problem that most draw-through maf-based cars (Isn't the Talon MAP-based?) face with a BOV vented to atmosphere. If you vent metered air, the computer doesn't know that the air is gone and you swing rich for a second between shifts or when you let off throttle. It just stumbles a bit in between shifts.

Plus, are we worried about the different air density between the air at the maf and the post-turbo, post-intercooler air? Isn't this one of the (many) problems with the maf pocation on the Stillen kit?
