It appears that the upgrade forces a login and many, many of you have forgotten your passwords and didn't set up any reminders. Contact me directly through helpmelogin@dodgecharger.com and I'll help sort it out.

I have a 73 dodge charger with a 2:71  8 1/4 rear end.  I would like to put in a 3:55 and was wondering how much of an improvement I can expect with this change.  I still drive long distance on the highway and am shying away from 3:90 or higher.  Thoughts anyone?
