kenne bell

Stock 4.6 3v Kenne Bell kit Spectre short filter Vmp 3 core heat exchanger w/dual fans After getting the Tune, the car doesn't feel as responsive as it did before. Throttle used to be snappy. Now, when I WOT it, there is a lag, kinda like too much fuel was dumped or a spark loss. The dyno chart...

I found this sensor hanging under my front bumper. Its to the right of the heat exchanger. Any help identifying it would be greatly appreciated. 2010 Mustang Gt 4.6 3v Kenne Bell Supercharger VMP Heat exchanger(3 core)
