11-16 LML Duramax Fleece FMW 63mm VNT Cheetah Turbocharger

Installing a Fleece Cheetah Turbo on your LML Duramax can significantly enhance the engine's performance by providing a more efficient airflow compared to the stock turbocharger. Here's what you can expect and some considerations to keep in mind:

Performance Increase: The Cheetah Turbo is designed to increase power output, improve throttle response, and decrease turbo lag, making it a popular upgrade for those looking to enhance their truck's performance, especially for towing and heavy-duty situations. 

Fuel System Upgrade: Depending on the extent of the performance increase you are aiming for and the existing condition of your fuel system, you might need to consider upgrading. High-performance scenarios may require better fuel injectors and possibly a higher-capacity fuel pump to ensure adequate fuel delivery to match the increased air intake from the turbo.

Transmission Build: Upgrading your transmission is highly advisable when installing a turbocharger that significantly increases power output, like the Fleece Cheetah. The stock LML Duramax transmission might not be able to handle the increased torque without risking premature wear or failure. Consider reinforcing the transmission with stronger components and possibly enhancing cooling capabilities to handle the extra power.

Custom Tuning: To get the most out of the Cheetah Turbo, custom tuning is essential. The tuning should be tailored to balance the air/fuel ratio, optimize timing, and manage boost levels effectively for your specific setup and driving needs. Popular tuning options include using EFI Live or HP Tuners, with custom maps developed by a professional who has experience with turbocharged Duramax engines. It's important to work with a tuner who can adjust the parameters specifically for the Cheetah Turbo to ensure smooth operation and to maximize performance gains.
By addressing these aspects—fuel system, transmission, and tuning—you can ensure that the turbo upgrade provides reliable performance enhancements without compromising the longevity and durability of your LML Duramax
