My mechanic explained the reason for the need to break the gears in. He spoke with a tech from Ford racing who explained that even though the gears are made of hardened steel. Going through several heating and cooling cycles keeps the metal from flaking. Anyway after the install he ran it through cycles and then told me to take it easy. The cost to have it done was $400.
Actually the reasons are two-fold. You need to heat treat the bearings and the metal gear face needs to harden under heat and pressure. If you don't break them in properly, you can actually get to the softer metal underneath and then all hell is going to break loose in there.
glad to hear your happy with your 373's. Modings is so fun isnt it lol. And listen to everybody else on break-in periods. I did for about 500miles. Goodluck!

This would have to be done every time the tune is loaded yes?
When I change tunes, the tuner ask if I want to keep my previous change (gear ratio) so I select yes and proceed with changing to one of my other tunes and the programer does the rest.

I am showing amazing restraint and breaking them in. I have 157 miles left on the 500 mile break in. Then look out
The dealership can reflash for new gear ratio. I know the one I called wanted 100 bucks to do it. And 950 bucks for the gear install ..........i said no thanks

I dropped the car off while I was out of town and came back and they were done.
As far as a tune I am FI and just reflashed my tune with the updated gear ratio.
why in the hell would you not want a tune.they really make these cars performe great.hey and bkid you can always just send a email to bama thats what i did. dont have to talk to nobody he just sent the new tunes back for the gears.i think we douges custmers should all tell douge to get rid of this guy i would be one of the people.if a enough of us mustang owners that do moding said him or us i think he would go.
