Subaru WRX 08+/ Forester XT 09+/ Legacy 03-09 Respons TMS [T9001]

The GFB Respons TMS is far more than just another dual-port blow-off valve—it's a game-changer for tuning your vehicle’s performance and sound. Here’s why:

Key Features:

• Venting Bias Adjustment: The Respons allows you to adjust how much air vents through each of the two outlets. This gives you:
  • Full control over the blow-off sound, from silent operation (full recirculation) to maximum noise (full atmosphere venting), or anywhere in between.
  • The ability to avoid common issues like stalling, backfiring, or BOV-related problems, even on cars with sensitive airflow meters (MAF).

Performance Benefits:

• Better Throttle Response: Improved engine response for faster acceleration.
• Faster Boost Recovery: The Respons returns the engine to peak boost up to 30% faster than the factory diverter valve when shifting gears, thanks to the Turbo Management System (TMS).
• Unlimited Boost-Holding: Handles high boost without issues.

How It Works:

• The venting bias adjustment system lets you control the amount of air vented through the atmosphere and recirculation ports. Adjust the dial to fine-tune the balance, allowing you to choose the perfect mix of sound and performance.
