Questions?

[winged1dur]

I own a 2006 F350 6.0 DRW 4x4 chassis cab with a utility body. My 5year/100,000 mile warranty expires next month. The FICM works fine now, no issues, but I am interested in the FICM REPROGRAMMING AND ECM/TCM ROLLBACK and I have some questions.



1.) Should I have the latest “flash” done by the dealer first?

2.) Should I replace the batteries first?

3.) How does the remote programming work? (I have a Mac book Pro laptop)



My main objective is to increase MPG’s without sacrificing reliability. It is a work truck that hauls occasionally and plows frequently but never tows.
