The AAM Competition 4 Bar MAP Sensor is the perfect solution for precision control over high-boost applications. The stock MAP sensor works within a limited range, which causes inaccurate boost control and inaccurate engine ECM inputs at higher boost levels. This can lead to difficulties during tuning, and even dangerous over-boost situations. The AAM Competition 4 Bar MAP Sensor allows for reliable boost control all the way up to 44psi. No cutting or splicing of the factory wiring is required, as this sensor plugs directly into the original harness and is a direct fit to the factory sensor. Collect data more effectively and achieve a better, safer tune.
