Chevrolet Performance LT5 Engine Controller Kits

Unlike controllers from regular-production vehicles (which may or may not come with a used engine), Chevrolet Performance uniquely calibrates their LT5 engine controller kits for installation in older vehicles. They arrive with many features required for late-model production vehicles in the "off" position to prevent triggering diagnostic trouble codes, which could also affect performance or require additional calibration adjustments.

LT5 engine controller kits offer all the required components to plug into the engine and get it running—from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors, and even a throttle pedal assembly for engines equipped with an electronic throttle body. Chevrolet Performance LT5 engine controller kits also include detailed instructions to help you do it right the first time, even if you have no experience!
