well I got the 1st fill-up done and did a comparison between the overhead and doing it by hand 438.5 miles and 28.9 gallons of fuel so 15.17 mpg not to bad for 1st fill-up overhead read 16.3MPG so it's off. I am logging every fill-up so I can see what happens with the fuel milage versus engine break in. The truck was built 4-07 no updates or reflashes as of now have been performed I did already have a CEL went and got the code read at Vatozone it was PO131 according to their code reader it was o2 sensor code. It came on at 105MPH just seeing what this truck can do. I have my fingers crossed
