It is 200RPM higher than factory and works well with almost all mild turbo setups, this even shines with the stock turbocharger. With a stock turbocharger, your vehicle will launch harder and at part throttle, operate like a stock unit while driving normally.

• Billet triple disc
  
• Perfect for all around use(daily driver, towing, racing)
