A chip? Will this help improve my fuel mileage?
Hey Everyone, This is my first post here. I have owned my '01 7.3L for 5 years and pulls very well. I used to help my (late) Dad service the 7.3's and there were no decisions when it came to what I wanted in a towing truck. When I bought my truck, the owner had installed a chip a couple of years earlier. He swore it increased his fuel mileage. When I first started towing right after I bought it, I was getting approximately 11-12 MPG towing.
I have noticed over the past year or so, that my fuel mileage isn't as good anymore. I went on a round trip of 250 miles pulling my loaded 24' inclosed and got only 9.3-9.7 MPG !!!
My truck has been serviced on a regular basis and has 180K miles on it.
I can't remember the name of the chip he said he had installed. Seems like it started with a "P". Maybe it was a Prowler??? I can't remember. If someone mentioned it, I'd probably hit me then and jog my memory.
Could someone recommend how I could increase my fuel mileage either with a chip or other means?
Thanks in advance, Rich
