You can put it pre turbo but it will not read correctly and it will live a short life, best bet is 12-18" post turbo between 9 and 3.

I believe Thadds problem is a very short down pipe. I remember a thread on YB about this very thing not to long ago.

Pre turbo will kill it. However, if it's post turbo and you have a really short downpipe it's going to read garbage. There is no good solution in this case.
