A turbo change trades throttle response for top-end air, or replaces a worn factory unit with a stronger one. This one is the Calibrated Power Stealth Mach 1 64 drop-in turbo, part CPS200275, listed to fit the 2017-2023 GM 6.6L Duramax L5P, which covers the 2020-2023 Chevrolet Silverado 2500HD/3500HD. It does not come with an actuator. The seller says the actuator is sold separately.
why this one — A turbo is never a standalone part. Fueling and a tune have to come with it or the engine is worse off. This is the current version of the Stealth Mach 1 64. It replaced the older kit that shipped with an actuator, so check that your truck's actuator is in good shape before you count on reusing it.
