While I'm sure this has been covered, I searched and couldn't find a definite answer. I'm wondering what the ideal placement is for the EGT probe on our STi's. Mine was installed thru the heatshield on the passenger side of the engine bay (with the probe wire coming up and thru the firewall) and a few friends (who are far more knowledgeable than I) say that it's far better to have it before the turbo, then I hear it should be in the manifold.....can someone help me out on this? I realize my terminology may be completely off, but would appreciate any help! Thx.
