Don't get a greddy bov, they leak like a seive

 

im actually looking to get this NGR Performance Type-S Turbo Blow Off Valve.

 

Why? The stock BPV diverts enough air. Venting air to the atmosphere after the mass airflow sensor has already sent a signal to the ECU to calculate fuel needs based on the air amount will only throw off the air fuel ratio. Some say it's not much and only throws it off during shifts when you let off. Now if you plan to relocate the Mass Airflow Sensor and have the blow off valve before the MAS, shouldn't screw up anything. might need a retune. These cars are finicky.
