What is Plug in Performance?
Plug in performance refers to the modification of a vehicle’s engine control system, or software to achieve performance gains. This is usually performed with aftermarket engine management systems and engine chips. A scanner connects to the engine control system and, with the assistance of the chip, is able to modify a number of factory set options. Such as the air fuel ratio, which can directly affect a vehicle’s power output. Plug in performance gets its name because the device used to control the system plugs into the vehicle’s diagnostics port.
