Why do you need TCM Tuning?

Required for the best possible drive-ability

TCM Tuning is the best tool to ensure your engine is operating within its preferred rev range

Benefits of TCM tuning over stock include:

Refined shift schedule to take advantage of the wide Duramax Torque curve

Improved torque converter clutch engagement settings to allow lockup under heavy loads, planting the power to the ground and lower trans temps

Torque limitations adjusted to allow high RPM fueling in performance applications

2nd gear start in 4wd low range (can tap down to first)

Further adjustments are available for customers with larger than stock turbochargers or significantly oversized tires

TCM Tuning is especially important for trucks with:

Larger tires (35+)

Modified turbo(s)

Built transmission

Any modification that impacts operating RPMs

Towing

Performance

Optional 2nd or 3rd Gear Start for competition applications
