SCT performance tuners are one of the most effective tools for boosting the horsepower and torque of your Cadillac, Chevy, Chrysler, Dodge, GMC, Ford, Toyota, Infiniti, Jeep, Lincoln, Nissan, or Mercury vehicle. SCT’s handheld ECU programmers come with pre-loaded tunes for many 1996-2018 cars and trucks, including gas and diesel engines. Starting at only $399 with FREE overnight shipping, the BDX and X4 tuners serve as perfect tools for instantly increasing versatility and power, while the touch-screen Livewire TS+ and GTX give you expanded monitoring capabilities for those who wish to go even further.

Diesel specific options include jake brake (exhaust brake to increase engine braking while coasting), torque converter locking, aggressive tow/haul (more aggressive shift schedule keeping the engine in its power band longer). Pre-loaded diesel tunes include performance, street, towing (shifting is towing centered), and trans only ( for heavy loads).
