Late model GM vehicles without removable chips require the use of the JET Performance Power Control Module (PCM). It provides the same type of Power Tuning as a JET chip and is the most sophisticated tuning device for late model GM vehicles available. The JET PCM is a 20Mhz RISC computer that controls air/fuel, ignition advance, and transmission tuning for the ultimate power gains.
