I have a 2005 3/4 ton[auto]. Just installed my gauges and also put in the superchips flash paq. I pull a 30' 5'er that weighs about 11500 loaded pulling to yellowstone from utah on highway 20 through island park Iwas having to back out of it because of egt's[1350] and half throttle. just wondering if that was normal? flat ground running 73mph egt's are somewhere around 1000 to 1100 is this normal. Does running with different tailgate [louvered] help with wind and fuel economy?

 

My understanding is that around 12 should be the limit.

 

for a 04.5-06 1350deg should be your max. 1000-1100 is not bad.

 

Besides a Super B turbo, my truck is stock. My max egt's are 1200 towing about 4k. I have read on some of these forums that common rail trucks are good up to 1500 for short periods. I think 1350 with your load is fine. My brother 2002 defuels at about 1150. But his isn't a common rail. When I get a programmer, Iknow my egt's will rise, hopefully not past 1500 though. Either way, sounds like your egt's are safe.

 

Also, when I'm empty and driving the speed limit up hills, I get up to 900 easily. Hope this helps.

 

where do you have your probe, pre or post turbo?

 

I will run on 1350 for short periods of time, so did that get hot right there out of Ashton?

 

um, ill run 1450 towing uphill and not be worried. the new 04.5+ trucks have special heat coating. they can take 1450 easily. ive seen 1550 down the 1/4 mile and 1600 for about 10 seconds. You can pull at 1450. Dont backdown at 1350. 1450 is perfectly fine.

 

yeah that it is where got hot. Ihave a cold air intake thinking about 5" exhaust will that also help? about how much? what about runniing with your tailgate? Thanks for everyones help.

 

I hit 1250-1350 all the time towing a 10k travel trailer on major grades. All stock w/ pre-turbo gauge, no problems in the first 15k miles...

Good luck with your '06.

I hit 1400 towin all the time. I have gone as high as 1600 for a count of 2 empty rippin around town.

 

My pyro is pre-turbo

 

Are not different temps seen depending on "where" pre-turbo the sensor is located?

Mine is between 3 and 4 and I'm told that is one of the hottest locations. Those pre-turbo mounted in the downtube of the manifold probably see the "average" or coolest temps pre-turbo.

I'm just not sure when quoting temps pre-turbo we are comparing apples to apples. Please inform me since I just installed my gauges and trying to learn.

 

I have my Commander set to defuel at 1350* EGT when pulling our 11k 5th wheel and it has yet to do so. We have run in 100* + temps and some pretty good hills and it has never gotten to the point of defueling. My probe is pre-turbo.

 

im pre turbo too. When i was bone stock towin across canada I hit 1400 for a good bit towin up a long hill with my foot in it pretty good. I was havin fun blowin the doors off empty ferds with 26' of enclosed trailer behind me.
