Fast lsxrt question
 

What is this port for I bought the first intake and it had this jb weld on it covering the port I used the intake nothing was wrong just curious thanks

This is a new one

Thinking it is an alternate location for the map sensor that someone drilled and then decided to run it topside.

Thanks I have been looking around was gonna ask fast also

You could try looking on Fast's website for the instruction sheet. If they don't have it online they could also send it to you. I also have a copy I can scan and email you if they aren't helpful.
