    Stock boost of LF3 turbos is 12 PSI

    Just noting that the LF3 engine uses two small turbos which total 12-18 psi depending on gear, altitude, and RPM amongst other conditions. A Trifecta tune is currently getting up to 28 psi...

    As another note, the 2.0T in some GM models is pushing 21psi to get 295ft/lbs of torque with a single twin scroll turbo. The LF3 turbos are surely good for quite a bit more psi.
