Quick Ship SKU #: DT1160000020000-Main Duramax Tuner Stealth Mach 1 64 Drop-In Turbo (No Core Charge) 17-19 GM 6.6L Duramax L5P

The crown jewel of this turbo is a custom 11 blade compressor wheel that delivers a wide efficiency range and can flow 74 pounds per minute of mass airflow compared to the stock unit that only flows 60 pounds. It is built from light weight, yet strong, billet aluminum and will aid in reducing or even eliminating turbo surge when towing. On the opposite end of the turbo, the turbine wheel has been upgraded to a 10 blade to deliver a distinctive sound and provide better efficiency to reduce exhaust gas temperatures (EGT's) and reduce drive pressure when under load.

In order to properly match the entire turbo, a custom vane/nozzle ring assembly was built in-house at DuramaxTuner. This upgraded design features taller and wider vanes to match the larger turbine which provides superior high-load efficiency, yet still retains the factory exhaust brake and exclusive throttle response.

Finally, this is built from a brand new turbo and electronics, meaning no core charge, and has been pre-calibrated if purchased with actuator with no custom tuning required!

DO YOU NEED AN ACTUATOR?

If you're wondering whether or not you should buy an actuator to compliment your Stealth turbo, allow us to share our thoughts. The L5P actuator has a very low failure rate in the field. The fact that it's well-cooled and not in close proximity to the hot parts of the turbo means that it's out of harm's way. Unless you're experiencing codes that indicate actuator issues or know for a fact that your actuator is somehow damaged, we would suggest saving your money and retaining your factory actuator.
