Custom ECM tuning applications
Larger tires (35”+)
Modified turbo systems
Built transmissions
Vehicles with modified operating RPM ranges

Benefits of TCM Tuning: – Smoother, more responsive shifting – Improved clutch holding capacity with increased line pressure – Optimized torque converter lock-up strategy for better efficiency – Keeps the truck in the optimal power band when hauling heavy loads
