A turbo change trades throttle response for top-end air, or replaces a worn factory unit with a stronger one. This one is the Duramax Tuner DURAMAX TUNER STEALTH MACH 2 (67) TURBO W/ACTUATOR 20-23 L5P / L5D, listed to fit the 2020-2023 Chevrolet Silverado 2500HD/3500HD with the 6.6L Duramax V8 (L5P).

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. Kingz Diesel Supply lists it at $3975.00, and the fitment above is what the listing itself states, not a guess.
