Go Fast Bits DV+ turbo recirculation upgrade for BMW F30 335i N55 2011 to 2018

Unlock sharper acceleration, steadier charge pressure and seamless drivability with the Go Fast Bits DV+ on your F30 335i. This compact turbocharger bypass solution replaces the fragile factory unit and delivers instant pedal response with consistent boost control, all while keeping cabin noise stock-quiet. No whistles, no drama, just reliable performance you can feel on every pull and every upshift.

What makes it a must-have

• Direct swap for the OE turbo bypass assembly on the 3.0 N55 straight-six
• Keeps the original electronics happy for factory-like behaviour and smooth idle
• Noticeably quicker response when you get back on the throttle
• Holds boost more consistently between gear changes for stronger mid-range
• Addresses common pressure loss from the stock valve under load
• Engineered for durability so it is a fit-and-forget upgrade
• Recirculating design for stealth performance without vent-to-atmosphere noise

Real-world gains you can feel

Expect crisper on-off throttle transitions, more stable charge-air pressure and cleaner acceleration through the rev range. Whether your 335i is standard or remapped, the DV+ complements factory calibration strategies and supports tuned setups by improving boost management without upsetting drivability.

Compatible vehicles

BMW 3 Series F30 335i saloon with N55 turbo petrol engine, model years 2011 to 2018.

Why recirculation beats vent-to-atmosphere here

On mass-air and MAP-managed BMW engines, recirculating the released charge keeps the ECU data clean and the turbo spinning efficiently. You get faster boost recovery and a refined driving experience without unwanted whoosh or flutter.

Tried and trusted by us

We have fitted and run the DV+ ourselves and our customers consistently report a more eager feel, smoother shifts and dependable boost control. It is the subtle upgrade that makes your F30 feel tighter and more responsive day to day.
