Does anyone out there know about gettign updates (on the trucks computer system) on your truck at the dealership?

What do you want to know? The newer updates usually end up with less power and lower MPG.

This.

The aftermarket definitely has the upper hand on ECM/TCM/FICM software updates in the way of higher performance, more reliability, and a solution that is most appropriate to your specific truck.

What do you suggest for aftermarket?

The Ford mechanic I spoke to was dead set against aftermarket tuners but; he does believe in the aftermarket EGR coolers and replacing the oil cooler.

He took me out to the yard that was full of 6.0's that had tuners on them and they are all awaiting head gaskets because of the tuner.

And how much ****tier can my fuel economy really get?

He is referring to having your ECM/TCM/FICM rolled back to a better strategy (program). Depending on what your current stock strategy is, may effect stock power and MPG.

For this you aren't adding a programmer to add power. Check out Power Hungry Perfomance, Bill has found a way to roll back to a better OEM strategy. Where as the dealer can't roll back to a better OEM strategy.


If your truck has been in for warranty work by you or the past owner, then it's a good chance the dealer flashed the ECM/FICM to the newest strategy for your year. The down side is, loss of power and MPG.

The truck was owned by a construction company in AK; it got a new motor at 80,000 (right before I bought it) so I dont know if it was flashed by a dealer.

Can I get it undone or redone?

you can go to the dealer and have them hook up the ids to check if there is an update. its takes about 5min if that to find out if there is a later calibration.
