Throttle Position Sensor (TPS) Enhancer for Grand Am Alero

The Throttle Position Sensor Enhancer maintains maximum horsepower by optimizing the throttle signal sent to the PCM. At about 70% throttle, the TPS Enhancer locks into maximum voltage which assures maximum power enrichment meaning once you hit 70% throttle it tells your car's computer that you're at 100% throttle. This should help initial acceleration by providing more fuel to the engine when you first accelerate hard. This unit also corrects for dead spots or flat spots in the throttle position sensor. Simple 5 second plug-in installation.

NOTE: This unit fits almost all GM engines including all years of 3.1L and 3.4L vehicles. It fits on all GM engines with a small, round, TPS connector except supercharged engines, LT1, and LS1 engines.
