I was reading my service manual for the 2013 SHO and I found something interesting. 
This is what is commonly referred to as the second MAP sensor for our cars. However in this manual it’s being called a “boost pressure sensor and CAC temperature sensor.” I know that sounds synonymous with MAP sensor by another name but then I found this just one page later:

There is another sensor on the outlet of the CAC?? And this sensor is being referred to as a MAP sensor as well. So the reason I bring this up is there are people on the platform having MAP sensor codes or boost issues and maybe this sensor is to blame? I may be way off but I just thought it was odd to have what is being called the lower MAP sensor actually being called something different. Could help in troubleshooting but if I’m wrong I can take this thread down to avoid confusion.
