This plug and play tuner attaches to four easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. Power gains on an otherwise stock car are up to 50hp and 60tq to the wheels. Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged.
