Wouldn't that EMAP sensor be better off if it was located in the DP anyway?

I thought you ran EGT pre-turbo, and EMAP after the turbo.

The point is to see the back pressure before the turbo. Post turbo emap would not give any really useful information unless the exhaust is very restrictive.

I wanted to see if I need to step up in downpipe diameter, but I guess that's just a one time use anyway.

Hmm... Why is that? (Sorry to derail the thread, I'm honestly curious).
