Towing with tune?

[crazeejames]

I have a 2003 F350 with a Gryphon with canned tunes. tow, race, extreme, 60,80,100hp respectively.
Can I tow in the 100hp setting with out wrecking anything?
In tow and stock mode, the truck seems to be a dog........when I tow in tow mode......7000lb trailer or so, my egts run about 1000F and mileage is poor.......same in stock. If I put it in extreme(100hp), it tows like a dream, egt's drop to about 850-900 and mileage jumps about 4-5mpg!
Haven't tried the Race setting yet. I drive all the time in extreme cause the tow tune doesn't seem to do much. Am I safe to tow in extreme as long as I watch TFT and EGT's? Truck has a shift kit and upgraded converter......just don't want to burn anything up, but the mileage and power is sure nice on the 100hp tune..........
Thanks

Yip, keep EGT's in check and you'll be fine.
