The Edelbrock Pro Tuner Supercharger Kit W/O Tuner #155923 is an upgrade intended for the 2016-21 Chevrolet Camaro ZL1 and Cadillac CTS-V equipped with the direct-injected Gen 5 LT4 V-8 engine. This kit is recommended for competition applications only and includes the R2650 TVS head unit only. It does not include all necessary parts for installation. The Pro Tuner Supercharger Kit #155923 is capable of delivering horsepower output well over the 1,000 mark with the appropriate supporting modifications, fuel system upgrades and custom tuning (not provided by Edelbrock). Note: Installation of this kit on a Camaro ZL1 will require hood modification in order for the supercharger to clear, and installation on the CTS-V will require modification to the strut tower brace to fit.
