I have a question about which tow tunes to order. My camper weighs 5600lbs. I had the truck and camper weighed last camping trip and the truck with 4 people in cab coolers full bikes loaded full of fuel in truck gross weight was 13940lbs. This will be pretty much the weight I would tow most of the time. I was kicking around getting the light tow 80hp it says up to 7500lbs. and the 65 hp tow tune also.

My question is what is the difference in these tunes will the 80hp tune run hotter egts? Can I pull in the mountains of Ky TN with this tune? Or should I get the 65hp and 40hp tow tunes.

Thanks

If you have a pyrometer, you can pretty well pull in any tune although the higher HP tunes are going to be harder on the rest of the drive train while under constant-duty load such as pulling up long grades.

The 65T program will allow you to pull without worrying about EGT too much as long as you don't lug the truck. RPM is your friend when pulling hard. The 80T will run hotter under load than the 65T.
