The GFB DV+ T9363 is a direct-fit diverter valve upgrade for the Cadillac ATS 2.0L LTG. It reuses the factory solenoid and ECU control while replacing the factory valve components with a pilot-operated design to improve valve response and boost retention.
Fitment Information
- Cadillac ATS 2.0L Turbo LTG, first generation: 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019
- GFB part number: T9363
Important Fitment Notes
- The factory black plastic protrusion and blue piston ring must be removed during installation. GFB notes that the plastic piece is brittle. If it breaks during removal, the DV+ installation can continue, but the factory diverter cannot be reinstalled.
- Do not drop the GFB piston during installation. GFB warns that an impact can cause hidden damage that may lead to boost leaks or sticking.
- GFB reports that a highly sensitive ECU may set a P2261 code after installation. Its troubleshooting guidance is to remove the short, fat main piston spring if this occurs.
Key Features
- Direct-fit replacement that retains the factory electronic solenoid coil, electrical connection and ECU control.
- Pilot operation uses boost pressure to move the valve piston progressively, instead of relying on the factory solenoid to directly move it through its full travel.
- Billet aluminum housing, brass piston and bonded silicone face seal replace the factory valve’s plastic components.
- Recirculates vented air back to the turbo intake, like the factory diverter valve.
- Designed to improve throttle response and recover boost faster after a gear change.

Product Description
The DV+ replaces the valve mechanism while keeping the factory solenoid coil and electronic control. GFB’s design uses the solenoid to operate a short-stroke pilot valve. Boost pressure then moves the main piston, allowing it to open progressively according to the pressure it needs to release.
The factory diverter can leak boost through its plastic valve mechanism. The DV+ uses a brass piston and bonded silicone face seal in a machined billet aluminum housing to provide a more positive seal. GFB states the valve can seal up to 50 psi; results on the car depend in part on the condition of the factory diverter being replaced.
Because the DV+ keeps the factory ECU control and recirculates vented air, it is not designed as a sound-making blow-off valve. With the factory airbox, GFB says there may be little or no change in sound.
