2016–2019 Cadillac CTS-V LT4 ProCharger Stage II Tuner Kit

ProCharger 1GY704-SCI Stage II tuner kit for the 2016–2019 Cadillac CTS-V with the original 6.2L LT4 engine. Excludes other CTS engines, earlier CTS-V generations and engine swaps.

Included hardware

The standard configuration uses a D-1SC supercharger, dedicated 8-rib belt drive, Stage II air-to-air intercooler, Bullet blow-off valve, charge tubing and replacement intake manifold. Fuel-system upgrades, injectors, programmer and custom calibration are not supplied.

Configuration

Select D-1SC, D-1X, F-1D, F-1, F-1A or F-1A-94 with satin, black or polished supercharger finish. Helical gearing is available for D-series choices only. Bracket finish, valve, intercooler, drive and intake-manifold options are specified separately.

Intake manifold

The standard replacement intake manifold is included. The port-injection manifold upgrade adds $500. Injectors, fuel-system upgrades and control/calibration hardware are not represented as included. Manifold and cover finishes are selected separately.

Required installation components

An ATI Performance Products 918856 balancer with hardened hub is required and is not included in the base kit. ProCharger specifies a maximum 10% overdrive crank pulley. Your installer must verify the existing balancer, pulley combination, intake configuration, fuel system and calibration before ordering.

Fitment and ordering

Provide the model year, VIN, transmission, engine modifications, planned boost, fuel and tuner details. This conversion replaces the factory supercharger; confirm the replacement intake configuration as part of the build.

Emissions

This tuner kit is not an emissions-certified complete system. Confirm intended use and registration requirements before ordering.
