FICM reprogrammed...worse fuel economy?
I bought my 2003 F250 CCSB 4X4 last October and around December I got a ECM rollback and remote FICM reprogramming and since I've can't seem to get above 15.4 MPG. Driving the truck back from Iowa when I bought it I got close to 17 MPG and now I can't even break 15.5 MPG, even on straight highway. Anybody else have this happen?

If you kept the inductive heating, you should be fine. I tried the non-inductive program one morning that was below freezing and she started but she sure wasn't happy for a couple minutes. Sat there and loped like it had a big cam, I thought it sounded cool but I'm sure the neighbors didn't at 6:00am. I put the inductive heating back on it...

May have to. How is that done? Assume that I need to contact Bill and get the programer back. I do keep her plugged in at night, but she will be outside during the day here in South Dakota. Our winters only get down the the -30's or so at times
