Put it on, you'll see. MAF cars don't like vent to atmosphere. The tial's stay open slightly at idle under vacuum, which means the car will not idle at all because its maf based. Basically the maf tells the ecu to dump fuel for X amount of air that was drawn through the meter. Then half that air escapes before it hits the cylinders, but the engine is dumping fuel for the full amount of air recorded by meter, so pig rich stumble blah blah blah. I wasn't guessing on the bov, not guessing here. Sell your tial, buy the recirc version unless you plan on going speed density by means of an aftermarket ecu.
