Thanks for the info yall. I knew about the MAP sensor in the manifold because it keeps getting oil/gunk on it (installing the Mcnally catch can tomorrow). I didn't realize it was a temp sensor as well.

Next thought/question - the IAT2 in the manifold is really stained/gunked compared to the one at the airbox and the one in the charge pipe. I've been using CRC MAF cleaner on it from time to time and I really notice a difference in idle/throttle response when it's clean. Is that something people replace to keep performance up or should I leave it after getting the can installed?

Hmmm - I misspoke in the air box. I know there's one after the air box not in it (I was generalizing). I may have to take pics - there is a sensor before the TB and one in the top of the manifold. When you remove them they look exactly the same but have different part numbers.

Ok I was confused - it's a map sensor in the charge pipe and a combo map/it in the manifold...
