EGT, how high can I go while towing.

This weekend while towing my 11,500lb 28' toy hauler w/four full size atv's, 480lbs of water, four adults and a dog my egt was between 875 to 925 on flat ground doing a steady 70mph and If I were to speed up to pass it would go up to 1200. My truck is an 08 with the latest Spartan tunes and latest Ford pcm updates and I was running the Spartan 210. Is this temp ok for long distance towing or should I step down to a lower tune?

Isn't that cooler than the stock trucks in regen?

Yes it is. I belive the temp you see now is before the turbo. The temp when regen was after the turbo. 1200 is OK but not on a long pull hard pull. Just back out of it.

Would I be better off going to a lower tune? Im only doing 70 when Im seeing these temps and the truck doesn't pull very well below that speed because it wants to stay in overdrive, Im saying that the engine lugs. I feel like ever since ford did the update things just are not the same with my truck like my egt. Also I do not have the dpf or cat on the truck and when I did, the regen temp never went over 1250 on the stock power setting.

Are you running in the Tow/Haul mode on your transmission?

Are you running the 210 or the 210 Tow Performance tune?

Have you tried going [B]up[B] to the 250 tune? When pulling my 8,000 # 5th wheel into a head wind, my EGT readings were actually higher with the old standard 210 than the 250. My truck is a 2010 and I haven't had any factory updates since I bought it 20 months ago.

With anything below the 250 tune, your not going to see EGT's get scary high. With the safety parameters built in to the tunes, EGT's will stay in check. I would stick with the 210 or 210 Tow Performance since they don't cycle the EGR valve. That helps with keeping EGT's down.

I can't speak for the Ford update/s because the dealer's only touched my truck once since I've owned it.

I've towed with the 210 & 250 tunes and both are fine. As Jeff said, anything below the 250 tune has safety built so you really can't get in trouble. You can tow with the 250 tune as long as you keep a close eye the gauges and be smart about it.

I routinely see 1000+ when towing my 13,500 lbs car hauler and so far I've never had an issue. I do this about once a month and pull between 72-75 for 10 hrs at a time with 30-45 min stop somewhere in the middle (carrying 136 gal of fuel helps ). The 250 tune produced better mileage (.5-1 mpg) so that's the only reason I use it.

Good luck and happy towing.
