Running empty I see about 700* at 70 mph. My truck has a Quad Xzillaraider 160 with a 3.5" downpipe with a 4" exhaust and no cat.

Towing my 12' tall 13,000lbs 5th wheel at 65 mph up a slight climb I saw the following with my Quad set at 160:



Just for reference, this is what I am towing.

 

Empty my EGT's are anywhere between 750-900 at 70mph. Towing my 20' car hauler they are about 900-950.
I would go the IC route over meth.

 

the intercooler from banks is one of the very few products they make that i would recomend. the highest egt i have hit with mine was around 1200 and that was climbing up eisenhouer pass on I 70 12,000ft el. on SL given it HELL...... typically my egts dont get over 950 normal driving on the interstate. also another thing that would help you out ALOT is taking the cat off and reaming it out and putting it back on im not sure what kind of emmsion tests you have to pass if its just a visual or if they actually hook up to the exhaust. but if nothing else atleast get the bigger downpipe you can still hook your factory cat up to a bigger downpipe.

Man you are very brave pullin that camper with you chip maxed out i hope you have head studs

 

it just hit me. are these EGT reading PRE-TURBO or POST-TURBO? there is a big difference here between the two. where is the EGT probe?

 

The probe was placed in the bend of the exhaust manifold. I assume that is pre-turbo.

 

yes if it is in the exhaust manifold and not the down pipe then it is pre-turbo. if those numbers were post-turbo then there would be a definite problem.....

 

Yes my truck has head studs.

My boost numbers are generally no higher than stock and my EGT's are typically lower than running on stock levels.

My probe is located on the driver's side exhaust manifold just before the bend.

 

do you still have you egr on your truck???

 

For now.

Trust me I am not one that beats on my truck when towing. If I am pulling a longer steep grade the chip will get shut off. When pulling a 6% grade the truck never gets above 2500RPMs which means 50 and 55 most times. I pull no faster than 65 mph on the flats. I'm just not in that much of a hurry. Personally, I'd love to have 4.30 gears in the truck so I could run 60 mph at almost 2,000RPMs.


Oh, and when my head gasket let go the truck was stock pulling a 6% grade up US95 out of Idaho into Oregon.

 

i forgot toturn my chip down one time while pulling some decent sized hills. my egts were smoking hot luckily i caught it before i melted it down
