I know the ideal place to mount the probe is in the exhaust manifold, pre-turbo. Is it OK to mount is post-turbo? I see alot of kits with the "header" probe that is held on with a hose clamp. Would it be OK to mount one of these in the downpipe? What kind of a difference in temp would there be between a manifold mounted probe and a probe in the downpipe?
