I'm getting a bung plug and taking mine out. I have that kit and the sensor is junk. Lasted 3000 miles. Just bought a new one.

Mine has 10k on it, almost all of these have similar bosch sensors. I at one time had the Innovate Motorsports one and it was woefully inaccurate. Got my EFI tune working perfect with the AEM almost immediately.
