Lil info for ya!!
The unique sound caused by a blowoff valve (but not a compressor bypass valve) sometimes comes at a price. On a car where the blowoff valve is mounted after the mass airflow sensor, venting to atmosphere confuses the engine control unit (ECU) of the car. The ECU is told it has a specific amount of air in the intake system, and injects fuel accordingly. The amount of air released by the blowoff valve is not taken into consideration and the engine runs rich for a period of time. Engines with a manifold absolute pressure regulated ECU or where the blowoff is mounted upstream of the MAF sensor are not affected.
Typically this isn't a major issue, but sometimes it can lead to hesitation or stalling of the engine when the throttle is closed. This situation worsens with higher boost pressures. Eventually this can foul spark plugs and destroy the catalytic converter (when running rich, not all the fuel is burned which can heat up on and melt the converter or leave heavy carbon deposits).
although the TIALS tight! haha. .

By the way, all the Z kits install it pre-MAF. If it's installed after the MAF it will cause stalling issues.

I don't really klnow what the SSQV sounds like but I absolutely love my Raptor's sound. All it is is a nice woosh of air with maybe a small shreak towards the end. None of that gay chirping sound from cars like the Subys and Evos.

But I have an HKS on my Gf's Sti. .I love it. .no problems sounds amazing and not one leak. .fits like a glove as well. .i'd go with HKS. .
