Drop-ins keep factory manners and exhaust brake with improved flow. S300 swaps move to a fixed-geometry performance turbo for race builds and big power; they need tuning and supporting mods.
Do I need to replace the actuator with a new turbo?
Not always, but worn actuators cause drivability and boost faults. If in doubt, pair your turbo with a new HE300VG actuator.
Will the Fleece Cheetah work on stock tuning?
Yes—it’s designed as a drop-in VGT upgrade for 2013–2017 trucks. Custom tuning can further optimize performance.
Pickup vs. Cab & Chassis—what changes?
Cartridge/part numbers and housings differ. Match the listing to 2500/3500 pickup or C&C to avoid fitment issues.
