: How high of EGT's are OK?

I have the Juice box and the installer set it at 1350. Alarm has sounded twice pulling a 30' trailer up a steep grade. I just back off on the gas. How high can you go on the EGT's before you are playing with fire?

do not go past the 1350. Make sure you use tow haul and overdrive by-pass and you should never get to 1350 driving sensibly. I tow a 40 foot toy trailer with quads and have only seen 1300 for only a couple of seconds.............oh and I have the Juice/attitude as well

On my "X-Monitor" by BD-Power the instructions say to set my pyro alarm for 1250'F pre-turbo installation and 1000'F post-turbo. I normally backoff if the reading gets to 950'F, but it takes a pretty steep and long grade for this temp to be reached. I'm talking the truck loaded with our 10.5' slide-in truck camper of course. Empty the truck never gets anywhere near max operating temperature via the pyrometer............SWH....

You won't hurt anything running it at 1400 degrees for a short period of time. The guys doing truck pulls are running 2000 degrees and higher with the same set ups we have. I don't see them blowing anything up. My LLY can hit 1400 degrees at the blink of an eye. I don't think it has hurt anything yet!! The most important part of running high egt's is letting them come down to 400 before shutting the truck off. This will save your turbo. Synthetic oil helps also. It breaks down at higher temps than dino oil.
