My son asked me if he could use my 99' F-250 PS to haul another truck on a trailer 200 miles. He is afraid that his 2002 Chevy truck will not have the power, even though there is no real climbing involved. My truck has the Diablo Sport set to high power. I do not tow anything out of town, so I keep it on the high setting because of the fun quotient. I am thinking of pulling the chip out and have him run stock. We may not have time to have the chip set for towing. Would it be a problem towing roughly 8000lbs in the high setting? Or am I being paranoid? I have a full set of gauges.
If you run the highest setting all of the time you need guages.. I have a 110 hp setting and 5" exhaust and with no load I can reach 1300* by 65 mph.
I would pull it..
If it were my son I would leave it in. You said you have gauges. My son understands what they are for. He would not melt mine down. At least he has not yet.
