2007Charger 3.5L - Original Backup and all tunes screwed

[charger2007]

I had the Axle Ratio set to 2.86 or whatever for winter, and decided to change back to the stock backup. Unfortunately now my charger is acting weird. I tried using the performance tune pref 93 octane without modification and it still seems to have issues.

Both Original Backup & Performance Tune 93 Issues:


1. Seems like rev limiter in drive is set low.. so max speed is now around 45-55mph (Foot to the floor and i go nowhere...)

2. Reverse stopped working for a while. I had to drop it into park and then into reverse to get it working. (intermittent)


So right now my charger is crippled and I have no idea what to do. Any help and suggestions would be greatly appreciated.


Thanks.

or whatever?

for winter?

huh?

what gears are in your rearend? thats what the gear ration needs to be set to....

You need to set your gears to what you actually have in the car. Changing the setting without physically changing out your gears in your rear end will cause damage to your car. It's not the tunes, or the Predator that's messed up....

Oh that is good...whatever? Only for winter?

Try just returning the car to stock tune dude then reload and don't mess with the canned program.
