Mirrors and PCM Reprogram
Hi all, I took my 2008 f250 king ranch 6.4L into the dealer for a PCM< warranty reprogram. It was suppose to fix the DPF cleaning from coming on to soon. I just got back from camping hualling a 33ft travel trailer. Last Oct. I was getting 11.9 MPG. Now 8.8MPG WTF. At 65 mph engine at 1500 rpm and turbo at 15 psi. At 70mph engine at just under 200 rpm and turbo at 30 psi. Is this normal ? before the reprogram it would run at 75 mph just under 2000 rpm and turbo at 10 psi. All test were in trailer/tow mode on shifter. Also still have problems w/ mirrors. go out and up but not in. Replaced switch still same problem and now just before the trip power telescope will not work. power fold still works. Any Ideas and tips would be a great help. Thanks in advance.
