Hey, wouldn't the EGT's go nutso when the truck is using extra fuel to clean the DPF?

 

From what ive gathered from reading, the exhaust heated up to its crazy high temp after the turbo

 

Mine is so hot most of the time its melting my mud flap

 

When cruising along on fairly level ground I am seeing about 850 post turbo (probe is mounted in the elbow right after the turbo). Occasionally I will see 1050 plus for a few minutes. I "assume" the DPF is being regenerated during this time. But have no way of independently verifying that it is.

FWIW I was concerned about my mud flaps, but they are still in good shape at 8500 miles.

 

Wow - 850 post turbo? That's quite a bit higher than my 4.5 post turbo. I usually run about 500-600, measuring with a post-turbo pyrometer.

 

"850 post turbo? That's quite a bit higher than my 4.5 post turbo"

Yes post turbo!

The probe on the 01 in my signature is pre turbo and runs closer to 650 / 700.

 

Wow - I guess I didn't realize they ran that much hotter. Learn something new every day. I guess in the grand scheme of things it's only 200 - 250 degrees...

 

At times I will run empty at 60-65 mph and see 950+ post turbo then maybe 10 minutes later it will read 510 and will cool to 400 at a red light.

I have mine installed pre-turbo and generally see 900 at 60-65 mph and around 1200-1300 during a regen. After 10 minutes or so it will drop back to 900.

How did your pre turbo install go?

On the 2007 I wanted to install the EGT probe preturbo but didn't want to drill unless I could remove the turbo before drilling.

After looking it over decided I didn't want to remove the turbo.

 

It went pretty well. I took a long time and drilled carefully with a well-greased bit. I have had it installed for several months and it seems to be working fine.

 

Will be installing a pyro on my Dads 6.7L this coming weekend. Decided on pre turbo and will use the old plug the exhaust pipe and drill with the engine running trick.
