I am getting ready to pull my new 44' toy hauler to South Dakota for a much needed vacation the last week of July and I have the option of using my daughters boyfriends Hypertech Three Stage Tuning system for this. My question is which should I put in the 35HP, 65HP or the 100HP? I am not going to be doing any other mods just this chip. I am starting from New Hampshire so there will be hills to start with, I don't want to do any damage but would like to boast my power and up the fuel mileage pulling this 18,000# Fifth Wheel trailer. Again this is just going to be for the trip out and back with us using my Harley Motorcycle converted to a Lehman Trike so there won't be any truck use out there as this is a motorcycle vacation. I know what you are thinking and I would only take the bike but the wife likes the comforts of a moving home on wheels after a days of riding. So members what do you think will be my best option? I would like the chip to be programmable on the move but this one is a 5 minute down load for each different setting. Beggars can't be choosy!
at the most, go with the 35hp, but honestly without the ability to turn it off on the hills i would just go stock. you may find you are backing out of it a lot on the hills. i dont see any gauges listed on your truck, and if you dont have any then stock is the ONLY option. your transmission wont like anything over 35hp in stock form while towing either...
