I have heard that grease is not a good idea because if any grease falls into the manifold the shavings will stick in there. At least till you fire it up and thru the turbo it goes.

Oh and yes my directions stated put the egt probe in the drivers side exhaust manifold.

Slick!!

It still has to go thru the turbo though.

I have also heard that this is not a good idea even though the shavings get blown out the hole some could possibly be blown thru the turbo.

I don't know about you guys but I want to keep the turbo out of the equation...Can you tell? LOL

Dan, I don't really understand your question as I did not even suggest that EGT's would increase 2,000* But....The different in pre vs post readings can be extremely different.

I think that it was RubberDuck that had both Pre & Post probes hooked to his rig and there was a very large difference, I don't recall the exact readings but they were above 500* and I think that they approached 900*.

Perhaps he will jump in.

I actually have that post Here:

But what i was trying to say was why would a post-turbo gauge go up to 2000*F?
I think it's pre turbo, and Slick seems to agree...
