Horrible noise
When it's cold out and my truck goes into high idle to warm up this extremely loud noise comes from my exhaust. Not sure if this is normal? I dot have a cat nor a muffler. It only makes this sound when its cold out and at high idle. Surely someone else has experienced this. It literally sounds like there is a jet plane in my drive preparing to take off. Anyone have any ideas? The truck is 01' f250 with muff del and intake.
Thanks

If your probe is in the exhaust down pipe, you are not getting a true reading of the EGTs. Change it to the exhaust manifold and drill and tap. Or drill and clamp to the up-pipe on the drivers side.
You are post-turbo and want to be pre-turbo.

But I agree with most around here that post-turbo reading is not the desired place to read EGT. I'm more worried about the temp closest to the heads, where the damage would be done. Why would you care about temps after the turbo, the gasses have had a chance to cool. How much did they cool? I would say that's a guess at best, unless you pick up both temps.
In short, I'd move it pre-turbo and get the proper gauge.

Along these same lines....when the EBPV activates isn't the truck supposed to go into high idle also? The past few mornings it hasn't been too cold here (upper 40s I guess) in South Texas and I have noticed that my EBPV activates and I get the jet engine sound but it is not going into high idle. I can remember cold mornings when my truck would go into high idle with the EBPV. Is it just not cold enough for my high idle to kick in?
