Towed the camp trailer, a few questions..?
This weekend we went fishing and hauled the camp trailer. It is a bumper pull that weighs approx 5,000lbs fully loaded. I had used the tow tune by Vivian with the Jake Brake. The truck seemed to haul good and I think everything went well. It was about 250 miles and 3.5 hours each way on a lot of mostly flat land, but there was a few large hills.
Here are the questions I have:
A couple of times this trip on the long or steep hills the ECT would hit 230 degrees and the EOT would hit 240-242 degrees. It was also 95 degrees outside. Is that too high, is there something I should be worried about?
Also I noticed that the truck would "turbo fart" almost all the time when I would let off the pedal. It doesnt do it that much when the truck isnt towing or when it is tuned with the looney tune instead. Is the "turbo farting" a result of the towing, the tow tune, ???
I was also towing the 5,000 lb trailer at about 65-70 mph, tried to keep it under 2000 rpms except for on the hills, and over all I was trying to be easy on it. I only got 9 mpg, I was hoping to get better than that with the tow tune and a light trailer. Does that mpg seem low for what I am towing?
