You said you do a lot of highway driving, so maybe this will help. I just got the 3.73s put into my car, and at 70mph my RPMs only increased 200-350. The drop in MPG is so marginal, I think it is well worth the modification.

Yeah RPMs will increase at highway speeds. The steeper the gear the more the increase. The catch is to put the car at it's optimal RPM point for MPG which unfortunately isn't so straight forward.

Now is this an auto car? Cause I could deal with that.

Sorry I forgot you were an auto, I am a manual. Not sure how different it would be for an automatic.

:-P had I been shopping for a mustang it would have been a manual gt, but this was left to me by my grandfather when he passed and being as he just wanted the look it's an auto v6, so I'm making due lol
