Putting together a DIY build. Where should I put my EGT thermocouple? I was thinking just before the turbine after the pipe. What is the best location for tuning?

Use an AFR guage instead. EGT has its merits, but in a turbo app. AFR is more important.

I think I have the EGT plan figured out so now onto AFR. Where is the best place to weld the bung? Collector in y-pipe? Post expansion chamber, pre-turbine, post turbine, etc. I'm thinking it may not matter as long as it can get a good signal. Post turbine would have the least impact on performance but with the wastegate it may be difficult to get a great signal.
