The factory turbocharger is known to stick internally and this causes the electronics to meltdown as they try to cycle and move the internals but cannot.
Installing just a turbo or VGT actuator requires you use Cummins software to re-calibrate the VGT. This Rotomaster drop-in unit comes pre-calibrated and is ready for install.
This direct drop-in replacement turbo replaces your bad stock turbo and electronics. Comes with a 12 month warranty.
