I have a new to me 2019 2500 6.7 with 12k miles, all stock, RFE68, non-ho, 295x65x20 and I’m pulling an 8.5k lb boat. I can hardly get to 65mph on an 8% grade on a 90degree day pedal to the floor, max boost 27psi and MAF reading 40. My son has an F-150 eco boost that will easy pull the same boat up the same hill at 70 with power to spare. Seems way wrong to me as I’m suppose to have nearly double the torque. Any ideas on what the problem can be ?
